They aren't super cheap. The self contained is around $4600-$4800 or so...shared kitchen gear load, food shopping and cooking for fifteen. Like Valygirl stated, a crapshoot on the social dynamics front...and sometimes a forced march of sorts...must go from point a to point b every day, but gives solid structure to a tour if one needs that. Many great stories and times with those groups...only a few bad stories, but some none the less.

Supported is almost twice the price as self contained, and I think there is still the shared cooking requirment. Social dynamics are what they are...

Neither of them are my cup of tea, but still a good way to go.
