The impression I get from this tour is that the paying public will be able to walk through the giant sets like the Ministry of Magic and the Hogwarts Great Hall?
Also, £28 for one adult is quite reasonable, I think. I thought it'd be a LOT more than that.
All I know is, my sister will be taking her daughters on the tour later this year. I might find a way to join them.
Where is the ticket site?
