My kids are twins - 7 years old and were able to ride everything. They had a blast. We werent sure to go to this waterpark or the one on Morey's Peir. They are right next to each other so we walked by both and then decided. Moreys was crowded with lines and older kids/teenagers plus more expensive. We decided on the Splash Zone and think we made the right decision. We rarely had to wait in line and the park never go overly crowded. The earlier you get there the better.
