An Amazing Place!

I can not say enough how happy I am with the experience we had with Atlantis Banquets and events. We had an afternoon wedding in the Seastar Ballroom. The planning was so easy. Our questions were always answered quickly and they stayed very consistent. Then, on the day of... Read More the wedding, I had zero concerns! I had a great bridal attendant who was so nice and took care of EVERYTHING (along with the rest of the staff). The room was set up beautiful, they set up everything as I had asked and more! Then they made sure everything ran so smoothly! I never had to worry! The staff was extremely kind and helpful to all the guests. And the food was amazing! I had guests tell me it was the best food they ever had at a wedding! And we were so full! As the bride, I could not have asked for anything more. The venue was beautiful, the staff was more than accommodating and kind, the food was incredible and everyone really enjoyed themselves. I would recommend having a wedding at the Seastar ballroom at Atlantis Banquets and events to anyone who would listen!

If you want a truly unique and memorable venue for your wedding reception look no further than Atlantis Banquets & Events. The day as a whole far exceeded our expectations from the moment we were greeted with champagne and strawberries, experienced a unique cocktail hour in the... Read More aquarium, and then enjoyed the reception in the beautiful upstairs room overlooking the Peconic River. The service provided by all of the staff was exceptional beginning with the initial planning with Craig Alexander to the actual wedding day with Lori, Jayme and Jacquie as well as all of the other staff who were attentive professionals that made the celebration run smoothly. The food served throughout the event was delicious and seemed endless. At the end of the evening our out of town guests had the convenience of staying next door overnight at the Hyatt Place East End. Many of our guests commented on how this was the best wedding reception they ever attended. Diane

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... Read More 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.

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.

From the start, it was a dream come true. Craig made us feel at ease throughout the whole process. Even when our wedding date had to be pushed back 1 year, he was very accomodating.

My husband and I started out looking to do a destination wedding, but realized we wanted to include people that we knew may not be able to afford such. So we started looking a little more local and stumbled upon the Long Island Aquarium. Initially, we were attracted to the... Read More place for the obvious reasons that it was an interesting and unique venue in a quaint little Long Island town. We ended up loving the place after we decided on this venue because of the quality of the service and the openness of the staff. Craig Alexander was extremely attentive to our needs as was the rest of his staff on our big day and everyday leading up to it. The food, even though we barely got to eat because of the usual wedding mingling, was excellent and all of our guests have simply raved about it. Other comments we get from our guests were how different and refreshing it was to be at a wedding where you get to experience beautiful and interesting sea life, instead of just drapes on the walls. My husband and I have not one regret about choosing Atlantis for our wedding and would absolutely recommend this wedding to any couple looking to do something fun and different for their wedding.

Everybody told me that planning a wedding is really really hard. So first thing we did was to look for a perfect place for us. We've been coming to the aquarium for years already and we love this place. We love everything about it. Then we heard that they do events and... Read More weddings here. We thought that the price would be outrageous. They have very good reviews from a lot of people. So we called and went there. CRAIG was the guy we talked to. HE IS THE BEST EVENT COORDINATOR EVER. He gave us a REALLY good price. AND we can get married inside the SHARK TANK!!! So we booked the place. Again, I thought its going to be very hard coordinating with them, being so far out (we live in queens). But nope, he made it so easy. The wedding day itself, everyone, all the staff, were so nice and so courteous and so attentive not only to us, but also to the details and the guests, and they took care of everything!!! (Bec I have no clue what to do). It was PERFECT! It was GORGEOUS what they did. Never thought my wedding would be that PERFECT AND BEAUTIFUL. Everyone loved the shark tank ceremony! Moriches Main Street Flowers (Ms. Judy) did such an amazing job with all of my flowers and the decorations! And they have a really good price too!!! Absolute entertainment and Photos of the heart made this day absolutely perfect. My Bridal attendant was SOOO attentive and SOOO nice! Everyone had such a great time!
