They are going about this all wrong. So they don't want to lift blackout dates because they don't want to anger Platinum Passholders? Yet they want to make all these cuts so that people who are paying a premium are now getting a lesser experience?
Orlando has had to lift blackout dates about every other year recently because Summer has become a much softer season over the years. Disney's has tried their darnedest to distribute crowds throughout the rest of the year and it's worked. Plus, the heat has gotten so bad here that you know what we call people who Disney World in the middle of the Summer? Brave.
If the fear is Platinum Passholders will be angry, even though I can't recall the last time Disneyland has had to even lift blockout dates, then appease them with some exclusives... a Platinum only park entrance, exclusive Galaxy's Edge time before or after park close on select dates, deeper discount on food or merchandise at select locations for a limited time, etc.
The money is there. The fix to these problems is so obvious to most of us. It's mind-boggling that they are putting their feet down on the lift this heavily.
