I'd like to know too!

Didn't do it when we went. It was bank hol weekend & there was no sign of her at her house, though we didn't try ringing her.

Got the impression the content could be adapted to what you wanna see/know about most. Her ad in the visitors centre clearly sez per hour, but whether that's per person or per group isn't absolutely clear on that either. It would seem a bit expensive if it was per person? Or would it?

There are folk around who have done it - hopefully they'll respond too.
