Here is the new 2013 edition of this listSorry for the really old bump, but this was a fantastic thread and I don't see anything even remotely similar on this forum anymore. Not sure if someone is maintaining a list like this anymore, but I would appreciate if someone can point me to one if there is. I'm not around here too much these days as I don't have any scheduled trips to WDW planned, but I still like to keep up with what's going on in the parks!
