Do the tent camping spots have room for more than one tent? Also, what's the parking situation like? (i.e. do you park where you camp or is there a parking area away from the campsites?)

There is usually room for more than one tent, but it depends on the site. People generally park at their site.

Depending on the site, sugar may vary. Most does have room for multiple tents and/or cars

Yes, lots of room at most sites. Parking next to your tent. There's almost always your pick of sites. Beautiful campground.
