I'd love to do the Tour de Mont Blanc and other similar treks. The fact that you're sleeping in shared, basic mountain huts has always put me off. However, now I'm travelling solo, I'm thinking it might actually be a good way to avoid the outrageous single supplements and meet some people.
What is it like. I'm in my 50s and suspect most would be younger? Does that matter?
I've seen a 4 day one in the Alps as a starter and am wondering how bad can it be?!
