How much does it cost per child forsplash pad? And how much to reserve large pavilion?

I believe the Splash pad is free. Sorry I have no idea how much the pavillion rental is. The premises are immaculate and the scenery is beautiful.

The splash pad is $1 per person, per session, and adults have to pay as well. There are two sessions, one from 10 to 2, and one from 3 to close. The entrance fee is cash only and they do not accept $20 bills.
