I don't think that would be a problem. People have birthday parties there.
Yes you can not a problem
Grant Park whenever I go to NY visited this place is a great place to eat and shop.
I think you can its pretty big ...just clean up the mess . It's nice there for a family for a picnic
Actually I have seen family being water slides and water guns. If it's a big event or an event where u rented the park I would assume you can. All they ask for is to not start fire so it could spread and to clean up after yourself. Safety is important there because the park is big enough for many youngsters and they ask u to be logical and smart
