My feeble detective guess at this early stage regarding the similar, yet worded ever so slightly different, emails that folks have been receiving:
I have a (cash) resort package w/ 5 day tickets booked, am not DVC nor an APH. It is for 9/7-9/13 at POFQ, a resort that I cannot see avoiding the chopping block if certain resorts are to remain closed. My ticket dates have not been extended (still say valid thru 9/14/20). Holding hope that we'd just be relocated to an open resort, BUT if others are already at capacity, a reservation such as mine would be super easy for Disney to just cancel outright (simply refund the cash). Seems the hopeful sentence email of priority access to the park reservation system may be going out more to DVC/APHs? Because even some folks who don't have active trips booked that received it may fall into one of the 2 camps above? OR perhaps Disney is waiting to see who cancels around our dates to gauge capacity if we're unfortunate enough to be booked at a resort that will be closed? Or it's just a standard Disney IT kerfuffle...
