I think the camping bit would be the least of worries - it's all pre-planned and organised, so it's not like you'll be beating bushes to find a place for your tent! I'm more concerned with the amount of sitting around. It's a killer on my back.

On the other hand, in a bus full of people you are friends with, there's that ease to stand up and stretch, get someone to give you a back massage, etc. I bet lots of marriages will come out of the OzBus!
