Hi dinger
I'm hoping to do mine end May and into June next yera. Like you, I'm camping, youth hostel, and if nothing else available, B&B's. Thing is, a lot of the accommodation books up early, and if you are planning your days, you need to know that you can get accommodation at the end of each one, so it ends up a bit of a catch 22. You have to book early to ensure your accomodation because everyone else is planning and doing the same thing.
I have booked one YHA (because very popular), so far, and made enquiries at a couple of places I intend to camp, just to make sure I'm not going to have any problems.
When are you planning to do yours?
