Atlantis Marine World Aquarium is the perfect venue for the nautical couple. My husband and I chose it after finding out they held weddings, we had gone there on many dates. There is nothing like tying the knot in front of an indoor lake and waterfall - especially when the bride makes her entrance on a beautiful wooden bridge. We were married in November 2004 and people are still raving about our wedding. People dined next to tropical reefs and the kids were entertained by the touch tanks - petting stingrays and bamboo sharks. For those who were not into dancing - there were tanks and exhibits to gaze at. They had the dinner line go through the Shark Tank cave so that no one was bored waiting for dinner - they enjoyed watching the sharks, fish and infamous sea turtle "Jaws". Their food was delicious - they had a buffet, there was something for everything. The baker did an AMAZING job - he made our cake exactly how we wanted it, I didn't want to cut it!! It was absolutely amazing and beautiful .... I suggest it to anyone!!

The food, decor and service were incredible!
I am still hearing compliments from my wedding. You wouldn't usually hear of a wedding in an aquarium. At first this sounds as though it would be cheesy and way too out of the ordinary. Atlantis turns this wedding idea into a sophisticated yet fun reception venue with all of the features of any other reception hall, but with the addition of an aquatic wonderland. First off, you can have the ceremony virtually anywhere on the aquarium grounds. You can get married outside on the docks, in front of a coy pond, between two statuesque penguins, indoors, or even in a shark-tank. You have full run of the whole aquarium, as there are no other guests there besides your own. Atlantis provides it own catering service and takes care of everything from table and centerpiece set-up, event planning, and even provides the wedding cake with design of your choice. The dinner tables are set up literally next to the fish tanks creating an underwater environment to keep your attention the whole night. The food was absolutely amazing, beating out any food I have ever eaten at any other wedding or restaurant I have ever been to. The staff provided service promptly throughout the entire process from booking and throughout the night itself. Contrary to popular belief, there is NOT a fishy smell in the aquarium as you eat. If you want a memorable wedding replacing fancy wallpaper and chandeliers with beautiful fish tanks and underwater adventure without giving up elegance, delicious food and amazing service, an Atlantis wedding is for you.
I can't have asked for anything better! Atlantis Marine World gives an amazing wedding! Not only is the aquarium gorgeous but the whole place is yours for the night! This is a unique and memorable wedding that screams fun! The staff is an A+, the food exceptional, they were so attentive to our needs and their attention to detail was perfection. They were open to any suggestions that I had and were always easy to get in touch with, very easy to talk to and we really felt like a pampered well looked after bride and groom. We got to pick out details to make out day unique to who we are.
AMAZING!!! This was the best venue possible. Besides being a unique facility, the best food, the best value, the staff are wonderful. Any questions that we had were answered right away. Any issues that came up during the wedding the staff dealt with on their own and I never even heard about it. They go out of their way to make sure your day is stress-free and perfect. The only slight drawback that we noticed is that the dance floor and tables are in two different rooms so when the wedding first started people weren't dancing... however the dj was able to get everyone in to dance. The aquarium is so neat because all of the displays are open so people can walk around and enjoy the beautiful aquarium.
