Yes, there is a wheelchair accessible port a potty
No
This is all outdoors rain or shine. All dirt/ grass ground, so due to the weather conditions lots of soft and muddy areas. No actual plumbing for indoor restrooms either. It's all portapottys.
It's not paved terrain, and does go up and down. There are some tough spots for wheelchairs or crutches. All the bathrooms are port a potties. I do remember at least one that was wheelchair accessible.
