Are there any hotel inventory aggregation platforms that focus on booking rooms for trips and events?

Yes. There are a number of hotel inventory aggregation platforms that focus on booking rooms for trips, group travel, conferences, and events. These platforms usually aggregate hotel room inventory, negotiate or display group rates, and help with room blocks or event accommodations.

Examples include:

• Cvent – widely used for event housing and hotel sourcing
• Meetingmax – event and group hotel room block management
• RoomRoster – group travel and event hotel booking
• HotelPlanner – hotel bookings for groups, events, and meetings
• Passkey – group reservation and event housing management
• Stay22 – travel accommodation discovery for events and destinations
• Expedia Group / Egencia – broader travel booking with group/event options
• Bókun / similar travel platforms – more travel-focused but sometimes used for trip-related lodging aggregation

If you mean platforms specifically for event organizers rather than general travelers, the most relevant category is event housing management / room block software. If you mean consumer-facing booking for trips and events, then platforms like HotelPlanner, Expedia, Booking.com, and Stay22 are more relevant.

If you want, I can also give you:

1. a shortlist by use case (events, group travel, conferences), or
2. a comparison table of these platforms.
