I'd really urge you to camp on site if you can possibly bring it off. You don't need to do much cooking if you don't want to, provided you bring a reasonable supply of cash - there's an ample variety of food vendors. You can have your choice of either food that's healthy for you, or food that tastes good. And there's even a beer truck, or has been in past years. If you play, or even just sing, the concerts are the least important part of the experience.

Just remember to bring an instrument that you don't care that much if you trip over a tent peg in the dark and fall on, while trying to walk and drink beer at the same time....

It's also a good idea to bring a good sharp jacknife in case there are too many enthusiastic drummers again this year.

Peter.
