The trend I've seen reported on here and in FB groups about moves that are 6/22-7/4 only, with NO modifying by the guest:
All Stars are being moved to FW Cabins primarily, I've seen a couple say SSR for them.
Pop is being moved to SSR primarily, but a couple OKW as well.
Moderates like CBR are being moved to various DVC rooms.
Deluxe resorts are getting moved to connected DVC or another Deluxe DVC resort. (I say "deluxe dvc" to indicate it's not SSR or OKW)
None of the above is set in stone. But it seems like they are bumping everyone "up" in some way. Value resorts to the less fancy DVC resorts, etc. Of course what they view as a upgrade may be different than how we look at it! We are DVC but LOVE to stay at Pop because of the Skyliner. If the parks aren't open most of our stay the Skyliner is kind of moot.
And they "seem" to be contacting guests about 2-3 weeks before arrival with this plan. Kind of nerve-wrecking, but I'm also thinking they are hoping some of us cancel for them. I know it's frustrating to not get your vacation back, but Disney themselves seems to be trying to refund as much as they can. If you've got flights involved through I don't know how long you can afford to wait for confirmation.
We have Pop starting 7/5 so we just missed this recent round of room moves/modifications. We have APs so we are hoping to get a little park time at the end of our stay, but a no park vacation wouldn't be bad in a DVC room.
