My Harry Potter obsessed daughter has been saving all her spending money so that she can afford an adult and child ticket for this tour. Have any of you been? Is it worth the entrance fee and the cost of a couple of train tickets to London? I can't bear the thought of her spending her money if it isn't any good. P.S. There's no way I'm going to be able to let her buy me a ticket - I'll pay for my ticket and the train fare, she can buy her own ticket.
