Yes to blankets and chairs.
You know Kelly, that's a good question. I have never been in the pavillion. However, I remember Rick Ross performing there last summer and when the lights went up there was fixed seating in front of the stage, but I don't remember folks gathering chairs, blankets, etc. I think you just camp out in the grass...The place is under much needed renovation as of June 4, 2018. Sorry I could be more definitive...Good luck!
Blanket yes chairs I don't think you can
Yes to blankets for sure.
