Can anyone help me please this is my first time doing a party for my daughter she is turning 5 and I already invited people and I have a day and time but I'm looking for a location still , I was thinking Riverside, I live in Redlands, most people invited are close to riverside so I'm having the party on a Sunday and how does it work if I have it at a park ? Can Ical the park and pay them to keep the restrooms open ? My main concern is restrooms for myself and guests a d I'd love to have outlets to, I am making food, making my own decorations and games and pries and goody bags, I'm searching for human ainment to like a magician, or balloon person.
