Dewey's 24 Hour Read-a-Thon discussion

We travel to so many places and times when we read. What are your favorite destinations (book settings)?
If books worked as portals to the world of the book you are reading, which book would you start reading this weekend to travel to that world? Would you go alone or bring someone with you?

I would be going to thee Invisible Library from Genevieve Cogman's books, and I'd be bringing my sisters, hopefully by getting them to buddy read the books with me. Maybe we could apprentice as Librarians there once we got in.

Hogwarts, Discworld, Middle Earth! I'd avoid Panem though, and Narnia might be a bit dangerous too. :)

I'd definitely read the Harry Potter books to travel to Hogwarts! I'd bring my dog, Ginny. :)
