Function Rooms near London

Without wanting to give too much away...
Someone has asked me to scout out possible locations to film some interviews for a forthcoming DVD/Blu-ray release.
My feelings are that as most of the people concerned almost certainly live in London or the surrounding area, then somewhere in the Herts/Bucks/Berks area might be best.
Does anyone have any details or indeed experience of hotels in that general area that hire out function rooms at a reasonable rate? I think hiring a proper studio will probably prove to be too expensive, but a nice reasonably quiet function room should do the trick. Plus, of course, there would be plenty of car parking space and facilities for the various interviewees to get 'refreshed'. Obviously I shall be doing a certain amount of 'googling' over the next few days, but any pointers would be gratefully received!
FAB !!!
