is it okay to show up for camping just for the 2nd night? If you have purchased, they will have a spot for us right?

It's really not a big deal. I go every year for multiple bands, multiple days. Many people only come for one or some of the nights when a band is playing for a long wknd, etc. If you have camping, you're in. They have a ton of space, and oftentimes have fields they aren't even using, or ones that only get used when the need demands. Don't worry about it at all

We have never had a Problem for a Site BUT We camp in Premium Camping with Our Coach and Trailer 69ft long and have always had plenty of room between us and our neighbors

Possibly, but not necessarily. It should be very warm and the camp sites at gorge have no shade and are not much wider than a parking spot at the mall.

Yes you may. Your spt was paid for it's yours.

Its not biggest deal

We just stayed the second night at Dead & Company. They really pack you in for general camping.
