We spent every minute we had  at Atlantis riding the slides again and again; checking out the aquarium exhibits; and wishing we had more time. I would certainly recommend coming for the day rather than not at all. But, if you can come and spend a few days, that clearly in the way to go. Mainly to have more time, but also to avoid the dreaded locker line where we waited a half hour for one cashier dealing with credit card after credit card (they don't accept cash) for all the folks who needed lockers, which is pretty much everyone not staying there.
I would not have called myself an amusement park or a water park kind of girl. But I really did dig this place. My daughter and I did manage to get lost several times while there. The place is massive. But I have trouble finding my way out of a wet paper bag. So I'm sure it's not that complicated and another few hours there and I would have been fine.
There is tons of walking to be done there, which I love. But I would highly recommend water shoes. (I am obsessed with my Five Fingers. Ugly. But brilliant.) Flip flops are not allowed on the water slides and my kiddo's feet were on fire for most of the day.
Atlantis is like a water wonderland for kids and adults. There's not much else going in the port of Nassau. So, this is an ideal place to spend the day if it's on your cruise itinerary.
