I agree that it is probably not unreasonable given what is involved, but I suspect that most self supported tourists are pretty frugal and would balk at $300 per day. My brother is fond of cruises and I don't think he typically spends that much for a trip where they wait on you hand and foot.

I think the only way I might consider it would be if it were a sagged fast tour. I am at least a bit curious what a trip like that is like. Still I am not sure if I would like that or not. The cost will most likely keep me from finding out. I just can't see spending as much for a week to 10 days of organized touring as I did for a whole summer of self supported touring on my own.
