Well, every traveler goes to WDW for different reasons. I have a Trip booked for June, one for August and one for December. August and December are paid in full, so I plan to go if the parks are open. June is the backup for my scheduled May trip that I expect to be cancelled and it is a room only I can easily move or cancel if necessary. All the rooms were booked at the discounts available at the time.
As an AP holder, I don’t feel I need to be in the parks from open to close. My typical park day is three FP, a meal, and some shopping and then back to the resort for R&R. I am content just to be there. So my personal touring style would work well under your scenario. There may be some others who feel the same. I know for many others, that would not be the case, and I will not judge their decision to postpone for a longer period of time.
