Mt Olympus has a few seperate hotels located on the strip away from hotel Rome that does have small pools ( like a motel or Inn does), but I'm unsure of the times and dates they are open. But the actual water/theme park has a pool called Delphi that runs 3ft all the way across if you want to check that 1 out. Be sure to go during the day because the pool of Delphi closes at 6pm.
No pools at hotel locations. Only at the actual park. Check out their hotel Rome option and see if there are pools there.
It is not the least. there are only waves that rather hit you
