Hi John,
We were very lucky to get a stay at the Kings House Hotel, expensive but comfortable! It is situated right on the WHW and what a views!
Also I can recommend te WHW-sleeper right on the station of Bridge of Orchy, Bunk beds but ver nice and special.
We made our choises for the accomodation that it was near the track, cause after a day walking any detour has to be avoided!
At Fort William the final is great in the Hostel right next door to the Ben Nevis. When you have time and breath left you can get up to the top, must be quite an experience.
We didn't, saved it for some other time.
As we are from Holland, I had to arrange evertything by Internet. We made the reservations quite early (january for the walk in May!). This is really to be reccommended as there are indeed not so much places to stay next to the WHW and the route is very popular.
Have a good time!, Louise
