About Atlantis Banquets & Events

Atlantis Banquets & Events combines waterfront event spaces on the Peconic River with celebration rooms inside the Long Island Aquarium. The Sea Star Ballroom has marina and river views, large windows, and an optional two-room division; aquarium spaces feature aquatic exhibits, including the shark habitat and waterfall. Couples can hold ceremonies at outdoor or indoor locations such as the Riverside Pavilion, Sea Star foyer, Riverfront Room, aquarium areas, or, by arrangement, inside the shark habitat. Cocktail hours and receptions can move between connected spaces, with the Shark Room often paired with the Coliseum Room for dining. The venue hosts one wedding at a time and offers customized catering, bar service, event coordination, valet parking, and bridal suites. Nearby hotels and a separate marina suite are available for guest lodging.
