I started there in 2013, and the starting point was indeed the Dornie Hotel.

And the Dornie Hotel website: Dornie Hotel

Has it changed? No irea, sorry. :)

Jeremy - I usually book a comfy hotel from where to start, usually well in advance, and I've never had a problem. Mrs B has required me to book a comfy bed for her every three nights or so this time. I booked them last week and now need to devise a route to somehow link the beds together.
Our first bed is at the Dornie Hotel, last year's signing out point, where a nice lady called Bridie took a £20 deposit for a £75 double room, if that's any help. They may not have many rooms left, if I remember correctly.
