Dunno much about PYB other than that they are regularly encamped up on Creag Meagaidh for their winter stuff (saw them up there last year during the 'distinct lack of winter' spell we suffered in these parts).
The lodge is good. At the minute they are going through a refurb in one half (in that its been demolished and is being re-built to tick a lot of eco-building bits). The food is good, everything there at breakfast from porridge to fry ups, packed lunches are provided then its back for cake and coffee at 5, off to a lecture and then dinner around 7 which is usually really fine, then there's the bar upstairs which is open to 11. Night Watch staff are helpful to.
The facilities are open to all residents regardless of the course you are on, so there's a climbing wall, pool, gym, drying room, dry tooling wall and other stuff. There is also the stores for the vital peice of gear you forgot and the two on-site shops.
The trainers in generally are good and know their stuff (always good to know) and always willing to answer any questions you have. Plus side to the lodge (if it floats your boat - personally I was not impressed) is its a short drive to the Aviemore wall if you feel the need to get away, but with most things available on-site Aviemore seems a long way to go.
