Is there a shelter that can accommodate up to 70 people? And is the pool close enough to the shelter to conduct a water baptism?

The park has shelters but I dont think it would accommodate that many and the pool is close but probably not for a baptism. They also close at 6:00 every day I think. There is football practice during the week on Monday, Wednesday, and Fridays for a youth organization.

The park have two canopies I think are good for 70 people

Does it cost money to get in??
