A couple of years back I talked to Critch Tramway Museum about a club meet in an area of their big car park.
They were very amenable to this on weekend days which didn't clash with other events. It is a super attraction for the family as well.
However we collectively decided to put it to one side that year.
It could really only be a single day meet, but there are nice sights nearby like Chatsworth (Pemberley in 'Pride & Prejudice' for those couch potatoes amongst you). Also the Peak District has caves at Castleton, Matlock Bath Spa Town, Buxton etc. Also nice hotels nearby.
I don't mind picking this up again.
