Atlantis is an awesome property. The only way you can use all the facilitie, however, is to be a hotel guest. Depending on how many poeple are in your group, you can reserve a room at the Comfort Suites (across the street) for the day as they have Full Atlantis privileges - including all pools, slides, beach, etc. If you don't want to spring for a room, then the Flying Cloud catamaran trip to Rose Island is a great snorkeling option.

Atlantis is breathtaking! We only had a couple of hours to enjoy it as we had to get back on the ship but it is definitely worth going to see. They have a huge aquariums filled with all kinds of marine life. I would however suggest going on your own as the ship charges a lot more.
We formed a group from our ship and took a private tour that went to the atlantis.The Driver we had was Lionel.He charged us $20 each he asks for more but will settle for 20. We couldn't use the pools or the beach but had a great tour which also included other parts of the Island. Have a good trip.
We toured Atlantis...It was very interesting, but the beach ( Paradise Beach ) was the best part....
You can go to Paradise Beach without going to the Atlantis...You'll love the white sand beaches and clear water!
