How to choose
Check the passes
Some hotels include water park access for every guest. Others cap passes by room type.
Measure the kids
Big slides often need riders to be 42" or 48" tall. Each hotel page lists the rules we found.
Toddlers need their own zone
A shallow splash area matters more than the size of the park.
Hours change by season
Weekday winter hours can be shorter than summer weekends.
Think about meals
Suites with a kitchen or kitchenette save money on longer stays.
