I LOVE OVERLAYS!!!I agree. I think a huge makeover of the castle is brilliant.
I also hope that they will start doing seasonal overlays more frequently. I would love a Nightmare Before Christmas overlay of Square Liberty for the last few months of the year, but I would not be surprised if many people would hate that.
Just give the Nightmare Before Christmas a land already!
Disneyland just kills us on anything seasonal, refurbishments, or maintenance. Please TDO beat Disneyland at its own game.
