Disneyland enforces a no show policy for Magic Key Holders! According to Disney Food Blog,
Disneyland began enforcing the Magic Key no-show policy this week after a six-month grace period when the penalties for skipping an advance reservation were not imposed. The policy states that “Magic Key holders who are a ‘no show’ for 3 reservations in a 90-day window will be unable to make new park reservations for 30 days. Existing park reservations at that time will not be canceled.”
