1- Italy: I've been to Italy and LOVED it. Set a book in Italy and I'll probably take an extra look at it.
2- Hogwarts: The best thing about the Harry Potter books? Hogwarts. I'm notorious for skipping along the bits that don't take place in the castle.
3- Narnia: How can you not want to visit a place where the animals talk?
4- An Animated Disney Musical: How much fun would it be to live in a world where you can break into song and not get stared at?
5- Castles: One day, I want to own a castle. It's one of the reasons I enjoy readings books about them!
