FWIW, my daughter had several reservations in October at ASMu. She got a call for each one from Disney travel. When we called back we were able to run through the options on each. Most were upgrades to CBR standard 5th sleeper, but the ones that began on Friday and Saturday were Cars section at AoA. Since our plans had solidified more since we made the original reservations, we cancelled a bunch and kept two, each as an upgrade to CBR standard 5th sleeper.
About an hour before the first call on Monday, I had reached out the the regular reservation number asking if the first reservation was still valid at ASMu and they said yes. I mentioned that there were people being moved and there were rumors of the resort opening being delayed. She laughed and said she hadn't heard anything about that. Sure enough we got the call about an hour later from Disney Travel directly. Clearly the regular reservation CMs have no idea people are being moved.
When I spoke to the very nice and very friendly guest relations CM, I actually asked her if this was about moving her reservation and she laughed. I told her what happened with the regular reservation CM and she said. well they were wrong. yes we are offering her to move to CBR standard 5th sleeper for the same price. It appears they have a dedicated team of 15 CMs handling this.
I asked what would happen if she declined and wanted to stay at ASMu and she said they have been told to tell people that they are strongly urged to accept. I asked if that was because the resort wouldn't be open and she just laughed and said they hadn't even been told officially why people were being moved.
Because we had about 6 reservations that needed to be moved by their records, I tried to wrangle an upgrade to a crescent lake area deluxe if we cancelled all of them to save them the time and effort and free up the rooms for transfers sooner, but she said the only options were CBR and AoA. As long as they still have availability there, I suspect that will remain.
Have to say that the friendliness and the knowledge of the people I talked to dealing this reminded me of Disney customer service from days past. very friendly and helpful. We had some conversations about CBR as we were trying to figure out what to do. I had done a little research once I heard people were moving and asked some questions that she was able to answer about the resort villages and the Skyliner. Definitely more knowledgeable and helpful than the usual CM.
