I just think they should've given more notice. I don't buy the "plenty of notice" line. Disney World and
Disneyland trips are sometimes planned a year in advance. Thousands of dollars were spent and were non-refundable before this change existed.
One of my children struggles with PTSD (as strange as it sounds, it has to do with access to bathrooms...long story), IBS, panic attack disorder, anxiety, and scoliosis. All these things combined make it very difficult to actively wait in line and be trapped in enclosed spaces for a long period of time.
I'm still hoping some flexibility is given outside of "developmental disorders." Our trip is scheduled for two days after the changes go into effect for Disneyland. We have been to Disney World countless times, but this will be our first trip to Disneyland. I'm hoping to find out more information with the change happening at Disney World first.
