Never been to The Making of Harry Potter? GO. Been to The Making of Harry Potter? GO AGAIN.
Because it is absolutely fantastic. LOVE The Backlot, LOVE the Hogwarts Model (took my breath away :P) and LOVE the way it started (I wont spoil it for you, but it's SO clever and just electrifying). SO good. Knocked on the door of No. 4 Privet Drive, hitched a ride on the Knight Bus, went shopping in Diagon Alley and got sent out from the Great Hall by the tour guide for being a Slytherin >:).
XDXDXDXDXDXDXDXD (spending WAY too much time with Sapph), loved the self tour part, loved the tour guide part, loved every bit :P.
