I don't know that anyone has been able to check in and travel that 60 days out yet, since it hasn't been available that long. I did it just about as early as anyone with
Dvc reservations could, at least as far as anyone reported here, and had issues with one of the dvc checkins (and our one non Dvc checkin). And problems at checkin that probably wasn't due to online checkin for another Dvc resort.
Fwiw with the Dvc checkin problem, the lady next to "our" CM said that she had done our packet just an hour before.
We traveled as "LILO" was being installed , and then this. No more software changes!
Oh, and I only remember getting emails fori one or two of our four online checkins for this trip.
