Disneyland Resort has paused sales of all their Magic Key pass tiers. Previously, lower tiers were still available.
Current Magic Key holders will be able to renew when their passes expire. Passes will begin to expire this summer, as the Magic Key program was introduced less than a year ago.
There have been many issues and complaints about the Magic Key program. Most notably, a lawsuit against Disneyland regarding limited Magic Key Park Pass availability is moving forward.
