Let me clarify what jimster03 said. There are two entrances to the waterpark; however, there are not people who check tickets. (The two entrance gates are there to keep people out when the waterpark closes). Once you are in the park, nobody will ask you for your ticket, or pass, again. There is nothing to worry about, you will be fine.
