I've not been myself, though I do definitely feel like it's somewhere I want to go at some point, especially if other Nintendo franchises get areas and attractions there.
No, but if I win 60 million dollars in the lottery, then hells yes. There's a lot of places I'd like to go, but our economy is so screwed right now, that it feels impossible.
Maybe when or if times ever stop being tough, they'll have a Wario Land/Ware area. If so, that'll definitely be the first one I'll be checking out.
