1. I hate to be predictable, but, obviously, I would want to visit The Wizarding World from Harry Potter: Diagon Alley, Hogwarts, The Burrow, etc.
The saddest fact of my life is that I live SO CLOSE to Orlando and yet.

(I also like to recycle jokes. SUE ME.)
2. I would also like to visit the Kingdom of Cello from The Colors of Madeleine series by Jaclyn Moriarty. But only during one of the nice color storms, please. And if I get to tour the palace, Jagged Edge, and the Farms with my girl Princess Ko and the rest of the Royal Alliance.
3. I would love to visit Camp Half-Blood and/or Camp Jupiter from the Percy Jackson series, but only during one of the down seasons when no campers are disappearing or being chased by monsters. So this may actually be one of those worlds I would want to observe from a distance since those poor demigods are never safe–at least not the Greek ones.
4. I also want to visit Crab Claw Key from the Summer series by Katherine Applegate. (Of course when I read the books, they looked like this, but that’s neither here nor there.) (I can keep up with the times is what I’m saying.) But that’s because it’s SUMMER and I am always in need of a beach day. Beach! Beeeeeeeeach. If I were in Crab Claw Key, my life would be this:

It would be GLORIOUS.
As for worlds I don’t want to visit, the first one that came to mind is Panem and the districts from The Hunger Games, which…obvious reasons are obvious. In fact, most of the fictional worlds I encounter and wouldn’t mind visiting have a great big old asterisk next to them anyway–simply because there’s usually a lot of strife and conflict happening. Otherwise, why would there be a story?
