hey..I'm looking at doing a camping one too. from what I've heard there isn't TOO much difference b/w the camping and concept tours, just sleeping on a thin mattress on a bunk bed or sleeping on an air mattress in a tent. People seem to really enjoy them.. Hope that helped a little
My friend did the 45 day Camping tour and said the pumps for the airbeds starting breaking about halfway through the tour, it didnt seem to put him off though. iv done the concept and i agree there probably isnt much difference between the two, concept is quite basic. im looking at doing the 3 week camp next year.
