This is every muggle's fantasy tour of all things Harry Potter. The Warner Bros Studio Tour has two huge sound stages and a back lot filled with the actual film sets, props, artifacts and costumes used to make the Harry Potter films.
Poke around Dumbledore's office. Creep down Diagon Alley. Sip a Butterbeer, munch Bertie Botts Every Flavor Beans (watch out for the green ones) and take a spin in the flying car. There's so much to see and do, it's easy to lose track of time.
Allow extra time for the second half of the tour and the gift shop. Beware, there's a magical spell in the shop that makes all your money disappear.
