What I am putting up is complete rumor, but does come from cast members so taking it FWIW.
My friend is currently at WDW and went to the site of PI reporting it as "a ghost town". The bartender in the bar he went to said that he couldn't mix him a "Kungaloosh" as they were "not allowed to make that drink anymore and if caught were told they'd be fired". Today, he was relating that story to a friend of his who is a cast member at Cinderella's Castle and was told "it's because the Adventurer's Club is going to have a surprise reopening around this Christmas".
Again, take it FWIW. I'm very skeptical myself, but shoot... I'd love to be able to once again salute the Colonel and go to another HOOPLAH!
