The Dr. Who Expo in Cardiff is located in a unit in the Red Dragon centre that is about the same size as a very small McDonalds. Exhibits are disappointing and some misplaced (info for one exhibit stands mistakenly by another). There is little interaction other than the green screen effect at the start which is probably the best bit.

We parked in the Red Dragon Centre, went to the loo, went round the exhibit, and got back to the car within 25 minutes so we didn't have to pay for parking. The highlight of our trip...

Had I have paid £3 I might've been appeased as there were some cool costumes to look at (Daleks, Kylie's maid frock etc), but £6 is far too much. Probably around 50p a minute...

I didn't spot anything in the shop that you couldn't get cheaper in Tesco.

FYI, if you still choose to go then be aware you'll need to use the toilets in Hollywood Bowl as there are none in the exhibition and no public toilets in the Red Dragon Centre.
