Can you bring small canopy’s? Instead of renting a shelter

You can bring a canopy as long as you place it along the fence line out of the way of foot traffic.

I saw people with little tents and pop up canopies. Call them, because I think it's allowed. They welcome families to come with coolers and picnics without the need to rent a shelter.

No

You will have to call and ask because I have never seen anyone bring one in.
