I have *ahem* 'inspected the facilities' at York House, havign only ever been in the downstairs. Mr. Adams kindly gave me a guided tour and discussed options.
What he proposes is to sign the whole building, all 3 floors of neo-classical glory (albeit substantially 'modernised' in the 1960s) to us for the weekend, with areas being openable on request. Facilities available which I wasn't aware of include a certain amount of computer use (for posting bulletins for non-attenders, and resolving lyric disputes) and a snooker table, for god's sake.
As I mentioned somewhere else, there is a soundproof room for music after the PEL stops, with a loft above which could be suitable as a quiet sleeping area. The main room, on the ground floor, is very large, there are various bits of squashy furniture which we can arrange to make it a comfortable loungy sort of place should we wish.
Cost is being discussed even as we speak, I'll post more when I get details. Now, any questions?
