Well, I've decided. I'm going to go. I've got some great friends who are going to keep a eye on me, as is one of the tutors apparently, so I should be OK. Thanks to everyone who's posted, either for or against me going, but I think it's best if I go (Added to which I don't want to be the only one that doesn't!!)
If I can get on the Net later I'll post and say what it was like, but they've arranged a theatre trip tonight and I've got a ticket so you might have to wait.
