I have been to the Atlantis twice, neat place. the first we stayed at the Harborside, it wsa awsome being that close but removed enough for some quite time. Just this past weekend, we were on the Carnival 3 night cruise, we were in dock over night, so instead of doing any kind of "excursusion" to the Atlantis, we went to Blue Lagoon Island, its just an island with a beach, you can walk around and check it out, swim, eat, also if you don't sign up for the Stingray City tour, once on Blue Lagoon, if you decide you want to, you can just sign up there, we had a friend that wanted to so he just walked in and signed up. Then after dinner, we got all dressed and left the ship and took a taxi to the Atlantis, I think they hit you for $4.00pp each way, not a big deal, just walk in like you are going to the Casino or shopping, (very expensive shopping)and you can walk the grounds, its pretty neat at night, there is a tunnel that you can see the fish, sharks, etc, and over by the Mayan temple you can see the fish also, it is pretty neat at night. Then after our walk of the grounds, we hung at the Casino till about 1:10am then took a taxi back to the ship. We saw Michael Jordan playing in the Casino, you couldn't miss him!!! There is a great Ice Cream place near the marina, it called Jimmies, if its warm enough, get an ice cream and check out the Yachts!
