Party FAQs

Can I bring birthday cake and put it in a refrigerator at the park?

Birthday cake/cupcakes are allowed inside the park with a purchased birthday package. The Park is not responsible for preserving cake and refrigeration is unavailable.

Do parents or party guests still have to pay if they are not getting in the water?
