My family went to the Doctor Who Celebration at Longleat, though I don't remember much about it beyond the queues (I met Peter Davison while in the queue - things must have got desperate if they were sending the actors of the Doctor out to keep the queuing people happy) and the exhibition. At one point I had some autographed postcards which I think I got at Longleat, and I vaguely recall purchasing The Tenth Planet novelisation in the shop but beyond that my memory's a blank which is odd because I was 12 so really ought to remember more.
