I think a big part of the problem with the timing/lack of communication is how much planning Disney makes you do well ahead of your trip. They have made it virtually impossible to have a impromptu vacation over the last several years. If they cancel your reservation 3 weeks out, it is very unlikely to get decent fast passes, ADR’s, etc. if you want to reschedule any time in the next couple months. While I totally understand we are in an unprecedented situation and do not envy Disney having to make these difficult reopening decisions, a lot of the “stress” customers are feeling is due to the hours they have spent planning their vacation and either deciding to try and do it all again or just move on.
