Last year was £135 so that's nowhere nearly double.
Take a look round on the net at what charges there are for trackdays now, bearing in mind too that it's a weekend and a noisy day, then tell me it's a rip off.
Last year was a one-off for lack of tracktime, but everyone only refers to that and not the good ones that there have been in previous years. There's no reason why this year should be a re-run of last year.
If anyone does drive like a cock in your group, complain about them to the race officials, so something can be done at the time. No point in moaning about it days/weeks/months afterwards.
