family camping

We're looking at an unplanned backpacking trip, our first with our 10 yo son. We want a mix of wildcamping and campsites. I'm thinking doing established trails in order to take advantage of established facilities en route. Any advice?

Just wondering how many people here would love to be able to practise thier hobby in the woods but feel they cant because they suffer from a dissabillity or they have child care issues etc. I know thats a bit of a in your face type personal question and I'm sorry if anyones offended by it, no...
