Subscribing to the thread because I'm interested.
Midweek trip is the way to go IMHO, I was there in late August and did a couple of laps midweek and didn't find it to be overly intimidating at all. If you're going to push yourself for a quick lap then go for insurance, it's a track that can bite hard. But if you just have a warm lap and enjoy the track there's really nothing to be worried about.
It's certainly something I think every petrol head should have a go at, it's a great experience.
