Our wedding was this past December at Atlantis Banquets and Events and I wouldn't change anything! They put on an amazing party and event. We got so many compliments and a lot of people, young and old, said it was the best wedding ever. Our wedding was detailed - I added a lot... Read More of things; favors in alphabetical order, things for each table, signs - I'm sure I was annoying in my details but they didn't bat an eye. Day of everything was exactly as we wanted it. The space is gorgeous. We had the ceremony in the Sea Star lobby with the grand staircase - walking down the staircase was such an awesome experience. Our reception was in the Sea Star Ballroom and out After Party was in the Aquarium itself. Our guests got a taste of the Aquarium upon arrival (the Manta Ray Tank) and then were amazed by the sharks and sea life after the reception. The food is outstanding! I'm a foodie and I loved my dinner and the appetizers I was able to try. Guests complimented the food a ton. We had the mini dessert hour, which included a huge array of cookies, pies, cakes, cordials and an ice cream sundae bar (another enormous hit) Bridal attendants, management and staff were available and easy to work with. Day of, there was always someone helping out and keeping us on track (and getting me drinks :) ) After the wedding everything was neatly packed up for us and brought to the Hyatt hotel next door. I can't thank Michelle, Caryn, Ashley, Lori and the staff at Atlantis enough for making our day so special!

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... Read More 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 greatful for that. All in all if you want something different, yet still the "long island" type wedding, this is the way to go!

Atlantis was the perfect choice for my ceremony and reception. The staff was absolutely amazing and the venue was gorgeous. I had a December wedding and the holiday decorations were minimal and classy, just as I hoped. The staff waited on me and my husband all day, we always had... Read More a drink in our hands, and they made us our dinner plates and even packed up leftovers for us! Our maitre'd Lori had everything running smoothly from the order of my ceremony, to lining the bridal party up to be announced, to getting the right people for photos. My bridal attendant Ashley was perfect, she was never in my way but somehow popped up everytime I needed her. She helped me with my bustle, refilled my drinks, gave me water, everything. This was the best experience and I would reccommend anyone to get married here. Ashley even helped me and my husband to our hotel room with our gifts, envelopes, and leftovers. The staff were flawless. The planning process was also a piece of cake, Caryn and Bryan always responded in a timely manner and honored all of my wishes.

On the day of our wedding, everything went perfectly. The staff was incredible and everyone was extremely helpful and courteous. Craig was a wonderful salesman - he's really the reason as to why we chose this venue. However, prior to the wedding, we did have some issues in... Read More preparing for the wedding. Certain information should have been provided to us early (such as the fact that food favors are not allowed) and the venue is not cheap - unlike other venues that will charge you 1/3 for a child, this venue charges you 50% (for example). Also, unlike many venues, if you have folks who can't make the reception, they make you pay full price 8 days prior (many venues make you pay that day). They won't be giving you your money back, even if you've met their minimum. The "extra" amenities you may want are charged - good example of nickel and diming you. Be sure to really ask questions, and really read over your contract. But can't complain about the overall result - the food was incredible and the venue is very unique.

I wish you could give zero. I recently attended a family wedding at this event. The staff is horrible.

And as I went to leave 15 minutes before the event ended the valet and the coat check were nowhere to be found.

My husband and I got married on April 23 and we had our reception in the aquarium at Atlantis. We met because we both studied marine science in college, so we knew from the very beginning of the planning process that we wanted to incorporate an aquarium or beach into our special... Read More day. We decided on Atlantis for our reception site. Since our very first meeting with a sales rep (Patty) to our last dance under the big shark, we couldn't have been happier with the care and attention paid to the most important day of our life by Atlantis. Our guests were struck not only by the beautiful space and being surrounded by marine life, but by the quality of the food and professionalism of the staff. Planning the day was also relatively stress-free (as much as planning a wedding could be, I guess). Our questions were always answered in a timely manner (thanks especially to Jayme) and all of our requests were accommodated. My husband and I are vegan so they worked with us to plan a unique menu that included more veggie-friendly dishes. These people run a tight ship and really seem to know what they are doing when it comes to planning events. I couldn't imagine a better outcome for our wedding. If you decide to go with Atlantis, you will not be disappointed!

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...

Atlantis was the perfect location for us to get married because we both adore aquariums. Our ceremony was in the lobby of the Sea Star Ballroom and it was set up to perfection. All the details we wanted were there and more. The processional was down the grand staircase and it... Read More really was a grand entrance. Our cocktail hour was in the Terrance Room and it was stunning. There was so much food and it was all delicious! Our guests could not stop talking about the food even months after we got married. Our reception was in the ballroom and it was magical. Lori made sure everything went according to plan and she was so well organized. She knows exactly what she is doing and if anything went wrong, I never had a clue! Everything was beyond perfect. I used to work in catering so I know how hard it can be to make sure everything runs smoothly and the staff at our wedding was the best of the best. I'm vegan and our chef, Sean, was super accommodating and everything I ate was delicious. I never wanted for anything and my husband and our bridal party were well taken care of. Adrianne was my bridal attendant and she was always getting me whatever I needed. Even when I did not know I needed it. I always had a fresh drink and food within reach. Craig and Jayme organized our wedding and they were always available for questions. My guests were even allowed in the aquarium during and after the wedding to check out all the sea life. My only complaint is the day went by way too fast. I wish we could get married here again.

This was our dream venue. We had our reception outside under the pavilion, cocktail hour in the aquarium and the reception in the sea star ballroom. I met with an event coordinator several times before the wedding. I reviewed every detail and outlined the entire wedding day... Read More with this individual. The day of the wedding this person was not present. Every single item I had brought in for the wedding decor had been reviewed with that person and since they did not actually work my event all items were placed incorrectly. The reception room was set up with the wrong gift box and all the items that I had gone over and outlined were thrown randomly anywhere some decorations were even missing and not displayed at all. The staff the day of consisted of a maître d, captain and bridal attendant all of which were a complete disappointment. The maître d and bridal attendent were extremely rude to our photographer and DJ. Additionally our bridal attendent was missing in action for the entirety of the day. When my husband and I arrived at cocktail hour we were forced to wait in lines for drinks and food. Not to mention I had to walk around carrying my dress with a detachable train waiting over 20 mins for someone to radio the bridal attendent to help me get my dress bustled. The staff most certainly did not make us feel like the guests of honor. This is a stunning venue however the service we received on our special day was very poor.
