Because of hip issues, I cannot sit in those low profile beach chairs .... can we bring regular size lawn chairs?

As long as there is no event restricting seating, you could absolutely bring some chairs with you.

Due to the wide open space. I would say yes, on none event days. If there's an event. It's best to visit that event's website to see if there's any restrictions on the chair style/size. It's possible if it's not displayed on the website. When you enter the event gates. Security will let you know.

Absolutely!!

Yes

Yes. Lot if open space

Yes....even hammocks

If you're going to a particular event, I would check with the venue first so you won't get stopped at the entrance. Otherwise, that sounds like a very good idea!

again if there is no events then yes you can I took it for my ant.

Yes you can

Yes you can. The park is full of open space, and it would not interfere on non-event days.

Agree completely with Maurice
