Wow, you got a response, he ignored my numerous emails and phone calls about his "open" pitlane at Goodwood that was timed sessions with a maximum of 30 cars that was actually 38, two 15 sessions by lunch, the rest queuing, two sessions by 4, the rest queuing, Dave was nowhere to be found.
Sounds awful.
Goodwood isnt cheap either, fortunately its fairly local so had no overnight stay, but still what do you do when you get up at 5, drive 2 hours and be told its timed sessions, in hindsight i would have raised issue immediately but thought i should try to make the best of it but soon realised there is a reason why i dont bother with timed sessions.
Forgetting all that, Dave's complete lack of response to emails and answer phone messages was the worst part. I had booked with Trackdays.co.uk, they also didnt want to know as they were instructed it was open pit by Dave (they also "attempted" to speak with him), i even took it up with my credit card company with a less than satisfactory conclusion (see below).
So lesson learnt, i will never do an opentrack day again and will never use trackdays.co.uk, i always try to find out who the organiser is and book directly as if you do have issues you will have a better recourse booking direct rather than with an agent.
