Myself and a pal did the ODP a few years ago. There is not the same camaraderie as when doing some of the more popular paths as a times you could think you were the only ones doing the route. We found sufficient open pubs for a luntime bevy en route. It is described in some guides as an easy route, which it is not. There are many stiles most of which are extra high, so a bit awkward for the shorter person. I use an altimeter and measured each days ascent. For the whole route the amount of climbing is over 21,000 feet! Some days were better than others, but overall, I enjoyed it and I am considering doing it North to South soon.
