You are dreaming. Galaxy's Edge will be a fine addition and spark a lot of interest, but demand will not be so high that it create stampedes and daily shutdowns of park entry. The biggest problems are going to be the days following when the daily blackouts end for passholders.This will prevent stampedes once galaxy's edge opens, and allow better staging of queues;
This entire "stardust" campaign is stupid. The solution to the overcrowding is to remove FastPass from some attractions, especially people eaters! The system is on so many attractions that it has created a scenario where every guest in the park is essentially two people. Your virtual self is waiting in line for one attraction while your actual self is off doing something else. MaxPass has only made this worse since it has taken away the effort that used to be required to obtain a FP. When are the higher ups going to realize that the system people love (FastPass) is the root cause of the thing that they hate (over crowding)?
