Thanks Guy, that's really helpful.
I'll go for the weekend ticket.

I've intended to go a few times with a group of Ultima friends but never got round to it. I was aware that they all stay in a hotel near Hinkley which is about 45 mins drive away. I'd never really given much thought to whether that was far away or not. I camped in a one-man tent at Stoneleigh one year for the weekend having driven down in the Ultima and I'm not sure I could walk upright for a week when I got home so unless the music line-up includes Pink Floyd being supported by Slade and Queen then I'll take the comfy bed option.
