I had a great afternoon at the Doctor Who Experience in the Olympia, London.
The first part is an interactive adventure. I won’t spoil the details for you, but it is great fun to be guided through the story by the Doctor. Especially as he made a comment that apparently was directed directly at me; I will be sure to check for feathers the next time I fly the TARDIS! The adventure is, of course, aimed at children, but the feeling of being inside the TARDIS is very well done, as is the space battle that takes place on board another ship.
After the adventure is the exhibition. This has a range of exhibits from classic and new Who, including a recreation of Doctors Five and Ten’s TARDIS console rooms.
The shop has a range of merchandise, some of which is exclusive. They also have special offers available to WiFi-equipped smartphones; you can grab a barcode that they scan at the checkout. I got myself a ΘΣ Φ ΓΥΔϟ t-shirt!

I was briefly trapped in the Pandorica, but thankfully managed to escape with some Timey-Wimey jiggery-pokery.

Awesome!
