The Tomasky-Dakin wedding I attended Nov 7 2015 was amazing. The staff of both the Atlantis and Hyatt were absolutely incredible. They were all very accomidating and all so friend and helpful. I would recommend anyone to have their event at the Atlantis Banquet.

My husband and I were married here in June 2012. We loved the venue for our wedding. It was beautiful and unique and amazing. I wouldn't change a thing about our special day. Also we loved working with Craig. He was so helpful and easy going. He made the planning go so smoothly, we had nothing to worry about! Definitely recommend having your wedding here!
I have been performing wedding ceremonies for approximately eight years never once have any of my couples or myself thought that Atlantis aquarium didn't go above and beyond everyone's expectations truly A great place to have a unique ceremony. Now that I am in Florida I still am fortunate enough to come back to Long Island, Atlantis marine world aquarium and still am performing there for the couples who request me keep the work up you're doing just great finally and respectfully Rabbi Judith and a special shout out to Fr.
