Castle Combe isn't an ideal track for a first timer. It's very fast, very bumpy - not a great combo.
The noise test is very strict, you don't get much track time (about half what you'd get on a 'standard' track day) and on top of that it's expensive.

Mallory is only 90 miles away, costs around £99 and is an easier track to deal with for learners. Silverstone is even closer, but is also more expensive, even than Combe!
