The truth is that I do not think it is allowed, they are extremely strict in the area designated for bathing, they do not allow clothes that are not swimsuits (no T-shirts, no sports pants, or pants or shorts that are not exclusively for swimming) also, with everything respect, I do not think it is a suitable place for such events (sectarian / religious rituals) I think it would be something uncomfortable that would disturb the Peace and tranquility of the place, since it is an exclusive place for "Family Recreation"
File for the permit..if you need it for a large party.
I think they don't allow Sundays, because the whole park is very busy on Sundays.
