Disneyland recently announced a new Magic Key program. It helps reduce crowding on high-demand days.
Disney will require visitors to make reservations before going to the theme parks, while continuing to block out access on the busiest days. The four options range in price from $399 per year for Southern California residents to $1,399 for the option with no block-out days and the greatest flexibility.
This new pass is only for Disneyland and California Adventure Park and will go on sale beginning August 25, 2021. More information is here.
