a few places near Flatbush (man to I miss Brooklyn).
New World Aquarium
1000 Island
Fish Expo
Brooklyn Zoo and Aquarium
My .02 cents
While all of these places are worth visiting, they arent nearly as high quality or will you find as much value as what is avail through this website and some of...
Atlantis is definitely a cool place. Kid friendly and great marine life. I stayed at an affiliated condo last time (lots of timeshare rentals as well) and it worked out becasue you had access to all the hotel amenities at no additional costs but the condo ended up being much more convenient...
I also had one for approx a year. Beautiful to look at and good addition to the reef but was sad it didnt live longer so I dont plan on purchasing another one. Good luck!
