We stayed in the "reef" section (2 adults and & 2 teens) about 3 yrs ago which had kitchenette and separate bedroom. Ocean views were outstanding but cost $$$. The coral section is old and on our first trip (over 10 yrs ago) we stayed there and were thoroughly disappointed.
Food cost are huge there so having a kitchenette to cook helps a lot. Just have your driver stop at the supermarket on your way to the Atlantis and give them your food stamps that you get at check out. It will be greatly appreciated !!!!
Cruise passengers are allowed to buy passes for the water park but we found they just mostly take up deck chairs and tan.
