I've visited Cardiff on nearly every trip I've made to the UK, and was happy that the Doctor Who Experience gave me an excuse to do so again. We had an entirely hassle-free trip and arrived at the YHA late in the afternoon, to find that all of the dorms had been named after actors who played the Doctor (we stayed in #3, Pertwee) and the luggage storeroom had a TARDIS motif. We enjoyed dinner at an Indian restaurant nearby, which had been used as a location in the show, and returned to the kitchen to use the wifi and met a group of very friendly young women who were watching Doctor Who episodes on a laptop.
The Doctor Who Experience is fun, and worth seeing at least once if you're as avid a fan of the show as I am. They have an impressive collection of original costumes, as well as props and reconstructions of TARDIS interiors. The gift shop is even scarier than the 3D movie of weeping angels, and I was lucky to escape with the shirt on my back plus the extra two I purchased from this very boutique. We then returned to the bus station via Forbidden Planet.
It would have been a nearly perfect day if I hadn't checked my email when we arrived back in London, to discover that I don't have any work at Murdoch next semester. So it goes.
