It's probably best to arrange to meet up with someone you know. I went a couple of years ago and felt a bit isolated. Everyone else knows each other and it feels a bit like walking into a big club (or in actual fact lots of big clubs) where you're the one outsider. Mind you, my opinions were probably coloured by my daughter having toothache and being thoroughly miserable for the whole week. Hope you have a good time - some of the music I heard was absolutely wonderful.
