1. Executive Hospitality & Demo Suites
(Presidential, Chairman & Hospitality Parlor Suites — 1,200 to 4,200 sq. ft.)
Booking via retail website prohibits commercial meetings, media shoots, or outside catering; hotel security shuts down elevator floor access for non-registered badge guests.

2. Hotel Business Center / FedEx Office Box Receiving Fees

Ship to Conventions.com Local Old Greenwich Warehouse ($0 Box Fee): We receive your pallet/boxes locally and courier them straight to your Hyatt Regency Greenwich suite or booth door on move-in morning.
3. VIP Restaurant Buyouts Inside Hyatt Regency Greenwich

Hyatt Regency Greenwich — Group Room Block, Meeting Space & Banquet FAQ

How much meeting space and how many guest rooms does Hyatt Regency Greenwich have?

Hyatt Regency Greenwich in Old Greenwich, CT features 374 guest rooms and suites alongside 30,000 sq. ft. of total indoor/outdoor meeting and convention space across 30 meeting rooms. Its largest ballroom spans 9,600 sq. ft., accommodating up to 1,011 attendees in theater seating or 711 for a plated banquet.

What is the true all-in nightly room rate at Hyatt Regency Greenwich during major conventions?

During peak 2026–2027 convention weeks in Old Greenwich, standard last-room rack and OTA rates at Hyatt Regency Greenwich average $389/night plus a $30/night resort/destination fee and 14.5% local occupancy tax ($480/night all-in). By contracting a 10+ room block through the Conventions.com Housing Desk (Sara Chaval · (702) 576-1312), exhibitors lock a $239/night group rate with the $30/night resort fee waived ($274/night all-in — saving $206/room/night or 43%).

How do banquet F&B minimums and the '++' service charge work at Hyatt Regency Greenwich?

To waive ballroom rental fees at Hyatt Regency Greenwich, groups typically commit to a cumulative food and beverage (F&B) minimum starting around $28,000 for the main ballroom. All banquet food, beverage, and in-house AV orders are subject to a 24% banquet service charge plus 8% sales tax — creating an effective '+33.9%' ('++') multiplier. A $148/person plated dinner menu item therefore settles at ~$198/person all-in.

Can we bring our own independent AV production crew into Hyatt Regency Greenwich?

Yes, provided you negotiate out 'Outside AV Liaison & Patch Fees' prior to signing the hotel group sales agreement. While ceiling rigging points in the main ballroom remain under the exclusive jurisdiction of the in-house rigging provider, groups using ground-supported truss towers and our MasterMSA Production Addendum save 45%–62% compared to in-house AV rate cards.
