Key West Marriott Beachside Hotel

Beachside Resort & Residences sits on seven acres along the Gulf of Mexico in Key West, Florida, offering a private beach, marina, and more than 11,500 square feet of event space across 12 distinct venues. The property accommodates gatherings of all sizes — from intimate beachfront ceremonies to grand celebrations of up to 1,075 guests — and pairs its event spaces with on-site catering and a dedicated events team that handles logistics from setup through conclusion. The Flagler Ballroom, the largest ballroom in Key West, offers soaring ceilings and flexible configurations suited to weddings, galas, and conferences. Outdoor settings include the Waterfront Patio, which puts Gulf views directly behind the event, and Hammock Beach, set directly on the sand for cocktail parties and intimate ceremonies. The Flagler Terrace adds a shaded open-air option for receptions and mingling between events. Room blocks are available for multi-day celebrations, and the resort's shuttle service, two on-site restaurants, and Brightwild Adventures marina keep guests connected to the island throughout their stay.
