I'm planning on staying Friday night, to avoid heading home on the M25 and M1 on a Friday evening which will almost certainly be a nightmare.
I'm keen to play Hindhead while I'm in the area, but I imagine it will be tricky to get on first thing on a Saturday morning so Friday afternoon would probably be best. Having said that, I don't really want to split from the group so if most people are playing 36 at Liphook on Friday, then I'll probably go with the flow.
Cheers,
James
