We visited Harry Potter Studios which is a train ride away from London and it was incredible!! I've read all the books and watched the movies numerous times so it was just amazing to wander through the sets and see all the displays. We watched a short video about the studios and then giant doors opened and we watched into the Great Hall decorated for Halloween. I almost got emotional it was so cool!
My daughter was there at the end of her 5 week trip to Cyprus, Malta, Portugal and the UK. She spent the last few days of her trip just outside London with an old school friend and they both went together. She thought it was amazing too.
Wow...my young ones have all read the books but I never did. I think life was particularly busy in that era. But love your photo and that looks like an awesome place to visit.
