Depending on the age/kid, Poly's splash pad might be a little too much for little kiddos. Mine loved it at ages 4 and 7, but a year earlier, I'm not sure if my youngest would have liked it. Grand Floridian has a cute splash pad, but my vote goes to Saratoga Springs. 2 pools with slides if they are adventurous, the main pool has a mini slide, and both Paddock and Grandstand areas have splash pads (the main pool has a small one, too but it isn't anything special). Grandstand's has an adorable horse racing theme, and Paddock's has kiddie slides. For moderates, we liked Caribbean Beach.
