I have some more info on our trip. We will be splitting our stay:
GCH Sept 22-23
DLH Sept 24-27
Just as an FYI for those staying at the GCH Sept 24-27: You will want to request a room away from the signature suites. There is a conference for test pilots and the large aerospace companies reserve the signature suites and open them as hospitality rooms throughout the week. The festivities last long into the night and as they provide a premium open bar, it can get a little rowdy
DH attends this conference yearly and I request a room as far away from the action as possible. It's interesting that this year they have offered us the option of all 3 Disney hotels, so I guess they're expecting a large turnout and want to spread everyone out. Anyway, just a heads up in case you see lots of people dressed up in a variety of military dress wandering around the resort.
