Terrible , the kids bought me this red letter day as a present in 2022 , was unable to book , website didn't work , couldn't get through on the phone so I extended the voucher for 50 quid . Then I wasted 3 days trying to book , nothing available. I did get through once on the phone and was told give it another month for the new dates to come out. Then wasted loads of time trying to book over a 6 week period . Then I started to read the reviews and the idea of having to wait around for hours for a 5 minute drive , while sharing the track with 12 year olds at 30 mph just put me completely off . I've let the voucher lapse. Good riddance, what a relief. Interestingly if you extend the voucher you only get a 9 months extension which in my case would be to end of May, so even if I was able to book before the voucher ran out , if I booked a date after May I would need to extend the voucher again so it would be current at the time of the experience other wise you get asked to pay the voucher cost again. I need this like a hole in the head.
