Went last June for 1 night and I never want to step foot in that place again! Of course my DD would love to go back! Pools are overcrowded with unsupervised kids. All kinds of junk floating in the pools by mid-afternoon and the water was cloudy by then also....disgusting. Very hard to keep track of your children on the waterslides with the sheer amount of other children who are running around without any parents in sight....saw lots of lost little toddlers crying for their mothers/guardians...as they were too busy to pay attention to them or just didn't care. Food court was a joke.....with 3 vendors open for purchases....Subway, a place that sold hamburgers/ice cream, and a pizza place.
Maybe go at an "off" time to avoid the mass number of kids and have the pools more to yourselves. Give me a Disney water park any day over the Nick hotel!
