Atlantis is exactly what the pictures portray. We just returned from a four day holiday and loved every minute of it. The Cove is exquisite. The rooms are well planned and luxurious . It is located at the further end of the resort, but still close to what we wanted to enjoy. The adult pool (The Cain Pool) is hip and lively, and the beach is beautiful . The sand is so soft and white. The only downfall for some is that the casino and night life is found at the center of the hotel (the Royal Tower), which is a bit of a walk. There are shuttle buses which can take you to the other towers if you don't want to walk. My husband and I are big walkers, so we didn't mind.
The important thing to be prepared for is the cost of food. We didn't opt for a food package. For breakfast we walked over to a plaza across the street from the Coral Tower. There we found a Dunkin donut shop, which had reasonably priced combos and healthy food choices ( ie. multigrain bagels). In this same plaza is also a small food mart (which has some fruits, cheeses, and crackers) and a liqueur store. The prices are still not what we are use to, but far more reasonable than the hotel. We also went to the fish fry, Frankie's goes Bananas. It was a true Carribean experience.
We felt you get what you pay for. It was worth it.
