MAC3: depending on when you're going, sometimes(ok most times) the water parks are just plain busy....typically, the pattern is you have a couple of hours when the waterparks first open that can be relatively crowd free....in the moderate to busy season, by lunchtime it will become very crowded and remain that way throughout the heat of the day....we have found that a good time to go during busier times is in the afternoon(say from 3pm on)...many times the waterparks start to empty as people prepare for dinner/evening park plans, another great time is during the rain...starts raining, people leave, you have the park to yourself...hopes this helps.....have fun
