Groups360, a provider of hotel booking and attendee management for the groups and MICE markets, today announced the signing of a definitive agreement with Hyatt to launch instant online booking capabilities for groups in early 2026, with the addition of Hyatt properties worldwide to the GroupSync Marketplace.

Through direct integration with Hyatt’s systems, meeting planners will gain real-time access to group room and meeting space rates and availability. The integration is expected to streamline the booking process, reduce reliance on traditional RFPs, and allow participating Hyatt properties to offer faster, more seamless service to MICE planners.

“As one of the leaders in the hotel industry putting this technology into widespread practice, we are meeting event planners where they are in this evolving industry,” said Steve Enselein, senior vice-president of events, Hyatt. “We are demonstrating our commitment to their needs and to the success of their events  by offering our Together by Hyatt platform. By offering instant group booking through GroupSync, we will equip planners with the instant insight and flexibility they need to tailor the ideal stay experience for each group.”

By deploying live inventory and group rates within GroupSync Marketplace, Hyatt will save and meeting and event organizers time by allowing them to filter and search using real-time room rates and availability. Once a property is selected, the planner may instantly book guestrooms, event space or both, as well as food and beverage needs and audio-visual equipment, all in a single online transaction. For larger or more complex events, planners may still send a traditional RFP through GroupSync’s proprietary streamlined process.

“Hyatt is one of the world’s most iconic hotel brands and has consistently demonstrated its dedication to group meeting and event planners and their guests,” said Kemp Gallineau, CEO, Groups360. “The inclusion of Hyatt properties in GroupSync Marketplace will serve to meet the evolving needs of the group meeting and event market, while positively impacting the experience for all attendees and stakeholders.”
