Don't know if this is relevant or not. I used to got all over the country on bike track days a few years ago, Brands, Goodwood, Oulton, Donny, Croft. Rode there and back. The long distance Jobbies meant a B&B stay the night before.
Trackday prices for Brands, Donny and Oulton seem to have gone up a lot more relative to Cadwell and Croft. I have a bit of a thing about not paying more than £100 for a bike trackday, hence I visit Croft and Cadwell more with a very rare trip elsewhere.

PS don't know if this is of any interest or how difficult it will be to get a place but but Leeming are doing an Airfield day for £45. Proceeds to Charity. More info. on
