AAs have the same guts.. and its not like they didn't know what the guys looked like so they couldn't design the dolls. They wouldn't need 8 months just to put one AA together. You don't run a company by waiting until you can physically do something to start it. They don't close the place before they know what they are doing, and have the work done, etc.
Having the HOP down for so long is actually pretty encouraging that its getting some good TLC and hopefully some enhancements. I would assume because there are so many AAs they need a lot of time to refurb them and they are going through them all. Otherwise, I can't imagine why they would close it for such a great length of time.
I wish we had more WDW rehab news here on the forum. No one has even mentioned UoE going down, etc.
