It was a lovely beautiful event. The staff was incredibly attentive. I thought there would be an issue with the music and the eating area of the aquarium, but seats and tables were placed by the dance floor so wall flowers could be part of the shenanigans
I loved having my wedding at the aquarium. It was such a beautiful venue, and I received so many compliments from my guests. The whole staff was accommodating and attentive to everything! I loved having the cocktail hour in the aquarium and then the reception in the ballroom, it was a very unique experience and wish I could relive it!
You will not find a more professional group of people to help plan and execute your wedding. Although we initially planned on getting married outside, due to the weather, we were forced to change our plans. They didn't hesitate in quickly setting up the ceremony inside and moving everything around. Everything was planned so perfectly. Everyone has been gushing at how wonderful the venue was. The food was INCREDIBLE, especially the grilled cheese and tomato soup bar. We have received so many compliments on our wedding. From initially planning with Craig, to finalizing our event with Jayme, it was an easy process. Lori, our maitre'd, was out of this world. If you are lucky enough to have her oversee your event, you are in good hands.
We had our Wedding here 6-5-16, and it was amazing!!! The whole team was outstanding - Craig Alexander, who we worked with from the beginning always felt like family and any questions we would have he would always address. Jayme who detailed the wedding was excellent and again any questions we had she always addressed. The day of wedding we worked with Carlos who was the captain, Lori who was the maitre d’, and Ashley who was the bridal attendant. They were great and kept the day running smoothly. There was never an empty glass, all 3 came over to us if we needed anything, and the guests were really happy. The day we got married it did rain, however, all of the aqaurium is beautiful, and again, the set up was perfect and on point and it turned out to be better than our original set up had it not rained. I also just wanted to give a special shout out to my bridal attendant Ashley - prior to the ceremony, we took pictures outside where it was very humid, my hair was a mess, she came to the rescue prior to the ceremony, she re-curled my hair, and was able to get the veil on! She also saved us some food and took everything from the bridal sweet to the hotel for us. Ashley went above and beyond for us that day and we will always be grateful for that. All in all if you want something different, yet still the "long island" type wedding, this is the way to go!
I loved everything about our wedding at Atlantis this past December! Their staff is amazing and professional, the price is great and they know how to throw a party. As soon as I saw that having my wedding at an aquarium was even an option I was in love - my fiancee not so much - but, Atlantis has a gorgeous building next to the aquarium for traditional weddings too. We ended up having our ceremony in the beautiful lobby, the reception in the upstairs ballroom and the after party in the aquarium with the sharks and sea life. It was spectacular and many of our guests are still raving about what a great time they had. The food was tasty, I loved everything I tried. We did a mini dessert hour that just had an amazing amount of cakes, pies, cookies, pastries, cordials and an ice cream sundae bar (huge hit!) The staff is professional and easy to work with. Any request I made they were typically able to work with and everything was perfect down to the detail day of. During the wedding itself I always had a bridal attendant refiling my drink, keeping us on schedule and helping everything run smoothly. The best of all is that the groom and I had a fabulous time ourselves - we were mostly worry free on our big day. I highly recommend Atlantis Banquets and Events - it's a fabulous place to have your wedding!!
