I had a lot of fun today! Thanks so much for the tickets!. Unfortunetely, I didn't get James/Oliver autographs BUT I was next to them (if that makes any sense).
They have changed a couple of things at the exhibition, but I was very happy to see props of Harry/Ron/Hermione/Neville's clothes from DH2, and Godric Gryffindor's sword. I loved how, since its still winter they set up the main entrance to the exhibit (Hogsmeade Station), to appear as if it were snowing. If anyone wants to ask anything, go ahead.
Once again, thanks so much Vanessa! :D
