I have done many one week tours alone, but I find sleeping alone in the middle of nowhere in the tent rather scary. you cannot see out but they or it know where you are.
I wonder if I know anyone who would not scream a bit if awoken at 0400 by a donkey lunging into the tent looking for your food bag(corsica).
I have been known to put the tent up with some noise-making devices and myself concealed some way away under a bush. am I a pessimist?
hostels and cheap band b are fine. you can meet some nice people.
