I hope they don't open up the castle for overnight stays after the Dreams Celebration. I'm sure I'm in the minority here, but it seems to me like it would take away a big part of the magic. Imagine walking down Main Street and seeing laundry hanging out to dry on a window, people having a party up there, eating, drinking, etc. I'm not saying that's what is going to happen. This is just hypothetical. The whole point of the castle is that it's a "fairy tale castle" where Disney princesses live happily ever after, not where Joe Smith from up the street spend his vacation. That's just my opinion though.
