Oh crap, what have I started!
The more I think about a meeting room booking the more I like the idea...just the right amount of risk! As for a church, er, probably not. Despite my love of loose women, I had to go when I was a kid and I don't think that would work somehow.
Just been looking at meeting rooms in my local area, and it turns out that you can hire out the council offices for a reasonable rate...!
