Regarding levels of activity on track on the day you attended, experience providers will usually be hosting other experiences as well as the one you booked for on the day, including junior driving experiences. On weekends for example, it is naturally likely that it will be busier. Oftentimes, they are limited to what track layout they use by the venue owners, so this means the layout you drive on will oftentimes share this with others.
It is worth noting as well, that the same supplier at the venue of this experience does also run it on weekdays, which may be both quieter and more affordable an option in future. We're glad you still enjoyed it despite how busy it was. Thank you again for your feedback.
