I got an email yesterday and then one today telling me about updates for my upcoming trip to WDW for our honeymoon.
We knew this trip would be a busy time, we are going from December 19 - 31, 2017. Nothing went down, and most of the parks went up. No big deal as we have our touring plans, just need to double check them and do some tweaking. The TP is more important than the CL for any day.
My understanding is that they are needing to make adjustments, and this in normal.
