Admission: Varies by park. Some charge one price for the water park and rides while others charge separate admission for both. Hours for the water park may differ from the rest of the park.
Attractions: Just like amusement rides, water parks have height requirements for some of the more thrilling attractions.
Attire: Most have rules on what can be worn in the water parks, so check with the park before you go. Some don't allow swimsuits with metal buttons or zippers on body slides. And take along flip-flops for walking on hot concrete walkways.
