We're going to Saltburn and planning to camp..

WHat is the camping setup? We've heard that you have to pay or that it's free with a weekend ticket. Can anyone confirm?
Not being a skinflint, just that we'll be more into the singarounds.
It'll be our first English Festival , never having crossed the border for one till now. But looking forward to it...
Where would be a good singaround/singing session to start with?
