A fairytale wedding

My daughter and son in law just got married at the Aquarium!!! As soon as we met with Joan back in December of 2021 to book the venue we knew it would be a phenomenal place for a wedding. Joan was so easy to work with and kept us on track with everything. Bryan the event planner helped us when we were about 2 months away from the actual day. The place is magical. Beautiful. We had the ceremony in the boat house, the cocktail hour by the coy fish pond and the reception in the actual Aquarium. The staff was amazing!! Our guests were blown away!!! The food was delicious and the options were great!!! The entire wedding from beginning to end was like a dream come true and I’m sure our friends and family will be talking about this wedding for a long time to come. We took a vendor package for an additional 5000.00. It included a choice of florist , DJ, Baker and photographer. All of the vendors we chose were fabulous. We did add ons with the DJ and the florist. It was so much easier to have everything at your fingertips. The wedding was timed perfectly and the person in charge was great and accommodating. They really care about giving the bride and groom a magical day!!! We did two additions to the regular “something blue” package and both were of our choices were big hits. We can’t thank everyone there enough for a day we all will never forget!!! Pure magic and joy!!!

Unique venue, great service. Overall a great time.

I had the pleasure of working with Joan, at the early stages of my wedding planning. I also worked with Bryan as the wedding grew closer. My husband and I got married on wedding there on August 13, 2023. From the moment that we saw the venue we knew that this was the place where we wanted to have our wedding. We both love sea life, the place was so unique to host a wedding there. Atlantis Baquents and events also has a traditional ball room as well, however we wanted to have our reception inside the aquarium. We got married outside on the riverside pavilion. Although it was an hot day it was manageable. The cocktail hour was set up around the koi pond as well as inside the Riverfront room. My captain and Bridal attendant where just wonderful. They made sure my wedding day went smoothly, and where there when ever I needed them. It was a hot day and the captain and Bridal attendant made sure to pass out water to all of the bridal party during the photo session. The Food was excellent, we did a taco station for cocktail hour and it was so good. For dinner we did the buffet so everyone had a option to choose what they liked. Seeing the table set up and the atmosphere was amazing. All of our guests had a great time.

Exceptional Venue for an Unforgettable Experience

I have nothing but wonderful things to say about this venue. Everything, from the staff to the food, exceeded my expectations.

My husband and I worked with Joan and Bryan in the months leading up to the big day, and they were wonderful. Their professionalism and amiability put me at ease, and I can honestly say — as the bride — I was never all that stressed during the planning process.

I'd also like to give a shout-out to all the staff members who worked our wedding the night-of. My bridal assistant was fantastic, always checking in and asking if my husband or I needed anything. She even got us some extra entrees to take back to the hotel room. Also, towards the end of the night, I noticed my pearl bracelet (an old family heirloom) had broken. My bridesmaids worked with some staff to search the floor, and we ended up finding 5/6 of the missing pearls!

The care and conscientiousness of each and every staff member did not go unnoticed, and I definitely recommend Atlantis to anyone getting married on Long Island.

Many guests came up to my husband and I to compliment Atlantis as well — in terms of the pure uniqueness of the venue, how delicious the food was, and how great the staff members were.

Thanks to this venue and its very caring staff, my husband and I had a truly wonderful and unforgettable wedding.
