Key takeaways
- Groups360 GroupSync suits small groups of 10 to 50 rooms that want instant online booking without a formal request for proposal.
- HotelPlanner and Engine Groups are free for planners, with hotels paying commission or the platform charging no booking fee.
- Larger events still need a request for proposal, since room blocks above 50 rooms usually involve attrition terms and meeting space.
- Contract support is the main difference between platforms: Engine reads and negotiates terms with you, while most marketplaces pass hotel terms through.
- Always confirm attrition, cancellation, and cutoff dates before signing, since those terms come from the hotel contract, not the platform.

Groups360 runs the GroupSync Marketplace, which turns small group bookings into an online checkout. Planners can search 32,000 cities and book 10 to 50 rooms instantly at participating hotels, without contacting the property or running a traditional request for proposal. More than a million rooms are open for instant booking, and major brands including Marriott, Hilton, Choice, Wyndham, and Omni take part. For a regional kickoff or a small wedding block, that speed is the point: you get a confirmed rate and a booking reference the same day.
The limit is group size. Once a group passes about 50 rooms, or needs meeting space and food and beverage minimums, the booking moves back to an RFP process. Groups360 can reach roughly 200,000 hotels by RFP in the same place, so larger events stay on the platform, but the instant advantage fades. For groups of 10 to 50 rooms, GroupSync is the fastest option on this list.
What we like- Instant online booking at 30,000 hotels
- No RFP needed for small groups
- Covers major brands such as Marriott, Hilton, and Wyndham
Watch out for- Instant booking caps around 50 rooms
- Meeting space still needs an RFP
- Hotel side pricing is separate

HotelPlanner operates as a marketplace connecting group planners with hotels for room block requests. Planners submit one group request, hotels respond with proposals and rates, and the planner compares them side by side. The platform covers weddings, reunions, sports teams, corporate groups, and other multi room bookings, with a network of 100,000 group friendly hotels worldwide. It is free for planners, with hotels paying commission on booked rooms.
The trade off is support. HotelPlanner passes hotel terms through rather than negotiating them for you, so attrition and cancellation clauses need your own review. Response quality also varies: popular markets return many proposals, while smaller towns return fewer. For planners who run their own RFP process and want broad hotel coverage at no cost, HotelPlanner is a solid starting point.
What we like- Free for planners with no platform fee
- Network of 100,000 group friendly hotels
- Side by side proposal comparison
Watch out for- Hotels pay commission, which can affect quoted rates
- No contract negotiation service
- Response quality varies by market

Engine Groups targets corporate travel, with a team that sources proposals and gathers hotel responses for groups of 9 or more rooms. The platform charges no booking fee, and its main advantage is contract support: the team reads hotel contracts and negotiates terms with the planner, including attrition and cancellation protections that other marketplaces leave to the planner. That help matters, since group contracts can carry minimum spend and attrition penalties that are easy to miss.
The corporate focus means social events such as weddings may find fewer leisure oriented properties than on HotelPlanner. For business groups that want a second pair of eyes on the contract, Engine Groups stands out.
What we like- No booking fee for groups of 9 or more rooms
- Team reads and negotiates hotel contracts with you
- Sources and gathers proposals
Watch out for- Corporate focus may suit social events less well
- Group threshold starts at 9 rooms
- Hotel inventory leans business heavy

Navan is a corporate travel platform that handles group bookings as part of a wider travel program. Small groups of 1 to 9 rooms can book self serve, while groups of 10 or more go to a team or RFP path. That structure suits companies that already run travel through Navan and want group trips, offsites, and conferences inside the same policy, approval, and expense workflow.
Group pricing is not published, and Navan does not state a contract negotiation service for groups publicly. For a company already on Navan, adding groups is natural. For a one off wedding block, a free marketplace fits better.
What we like- Group booking inside a full corporate travel program
- Self serve for small groups
- Team support for groups of 10 or more
Watch out for- Group pricing is not published
- Works best inside an existing Navan program
- Less suited to one off social events

Groupize combines attendee registration with hotel room blocks, so a conference organizer can manage signups and rooming lists in one place. That pairing helps associations and corporate events where the room block and the attendee list must stay in sync. The platform also gives hotels tools to manage group business, which improves response rates on larger events.
Pricing is not published, and setup takes more work than sending an RFP on a free marketplace. For a simple 20 room wedding block, Groupize is more tool than needed. For a conference with hundreds of attendees, the registration link is worth the setup.
What we like- Combines registration, room blocks, and attendee management
- Strong for conferences and associations
- Hotel side tools included
Watch out for- Pricing is not published
- Setup is heavier than a simple marketplace
- Best for events with registration, not simple blocks

Tripleseat is a hotel side platform, priced at $400 per month, that helps hotels and venues manage group sales, event bookings, and banquet details. It integrates with property management and booking tools, so group leads flow into the same system as the rest of the property's business. Small and boutique hotels rate it highly for ease of use, and it suits venues that handle many small events.
Planners do not buy Tripleseat directly; they meet it when a hotel uses it to respond to their inquiry. Knowing that matters: a hotel on Tripleseat can usually turn a proposal around quickly and track rooming lists cleanly. For hotels choosing group sales software, Tripleseat is a proven option.
What we like- Built for hotel and venue group sales
- 15 verified integrations with booking and PMS tools
- Strong with small and boutique hotels
Watch out for- Priced for hotels, not planners
- No free trial
- Setup and training take time
#7Event Temple

Starting price$400 per month
Free planNo
Event Temple is another hotel side group sales platform, also starting at $400 per month, with high ratings from small and mid size hotels. It gives sales teams a clear pipeline for group leads, proposals, contracts, and event details, and it performs well in North America and Europe. Hotels that handle weddings, social events, and small corporate groups use it to keep leads from slipping.
Like Tripleseat, Event Temple is bought by hotels, not planners. For a planner, its presence at a property is a good sign for response speed. For a hotel choosing software, Event Temple competes closely with Tripleseat on price and ease of use.
What we like- Top rated for small and mid size hotels
- Strong in North America and Europe
- Clear group sales pipeline
Watch out for- Priced for hotels, not planners
- No free trial
- Less suited to very large portfolios
Starting price$400 per month

MeetingPackage helps hotels and venues sell meeting space online, with real time availability and instant booking for rooms and packages. Pricing starts at $400 per month for hotels, with volume based pricing at higher tiers. Independent hotels favor it for simplicity: a property can put group and meeting inventory online without a heavy sales system.
Planners interact with MeetingPackage through individual hotel websites rather than a central search platform, so it does not replace a marketplace for comparing many hotels. For hotels that want direct group bookings from their own site, MeetingPackage is a practical choice.
What we like- Real time availability and instant booking for meeting space
- Simple setup for independent hotels
- Strong user ratings
Watch out for- Hotel side tool, not a planner marketplace
- Planners reach it through hotel websites
- Pricing rises with volume tiers
How we chose
We compared planner marketplaces and hotel side group sales tools using published pricing, group size thresholds, fee models, and contract support, drawing on vendor pages and independent comparisons from 2026. Each platform had to handle multi room bookings for US or international groups. We weighted free planner access, instant booking range, contract help, and hotel coverage, and we left out single hotel booking engines since those do not compare across properties. Prices change, so confirm the current rate before booking.
Start with group size. Groups of 10 to 50 rooms can often book instantly on GroupSync, while larger groups need an RFP on HotelPlanner, Engine, or Groupize. If your group needs meeting space, food and beverage minimums, or a rooming list with many names, plan for an RFP even at smaller sizes, since those terms need a contract.
Next, weigh fees against help. Free marketplaces cost nothing for planners, but they pass hotel terms through. A platform that reads and negotiates the contract, such as Engine, can save more than any booking fee would cost if it removes an attrition penalty. Read the attrition clause, the cancellation deadline, and the rooming list cutoff date before signing anything, and get the final terms in writing.
Finally, match the platform to the event type. Weddings and reunions fit free marketplaces with broad hotel coverage. Corporate offsites fit travel programs such as Navan or Engine. Conferences with registration fit Groupize. If you are a hotel choosing software, compare Tripleseat, Event Temple, and MeetingPackage on integration with your property management system and on support hours, since a group lead that waits until Monday can go to a rival.
Frequently asked questions
How many rooms make a group hotel booking?
Most platforms treat 9 or 10 rooms as the group threshold. Engine Groups starts at 9 rooms, and GroupSync handles instant booking for 10 to 50 rooms. Below that threshold, standard individual booking usually costs less and carries fewer contract terms.
Are group hotel booking platforms free for planners?
Many are. Groups360 GroupSync, HotelPlanner, and Engine Groups are free for planners, with hotels paying commission or the platform charging no booking fee. Hotel side tools such as Tripleseat, Event Temple, and MeetingPackage are priced for hotels at around $400 per month.
What is attrition in a hotel group contract?
Attrition is the penalty for booking fewer rooms than the block guarantees. If a contract guarantees 50 room nights and the group uses 40, the hotel may charge for some or all of the unused nights. Read the attrition clause, the cutoff date, and any allowed shortfall percentage before signing.
Should I use instant booking or an RFP for a group?
Use instant booking for small groups of 10 to 50 rooms with no meeting space needs, since it confirms a rate the same day. Use an RFP for larger groups, groups needing meeting space, or events with food and beverage minimums, since those terms need negotiation and a written contract.
Can one platform handle a wedding room block and the reception venue?
Partly. Marketplaces such as HotelPlanner cover room blocks for weddings, and hotel side tools such as Tripleseat cover venue and banquet details at the property. A wedding that splits rooms and reception across two venues usually needs two bookings, so confirm both contracts separately.
How far in advance should I book a group block?
For popular weekends and conference cities, book 6 to 12 months ahead. For small groups in off peak periods, 2 to 3 months can work, and instant booking platforms can confirm rooms much closer to the date. Peak season and citywide events tighten availability first.
