Missing a Disney reservation in 2026 has different consequences depending on the type. For Dining Reservations, if you "no-show" or fail to cancel at least 2 hours in advance, you will be charged a standard fee of $10 per person on the credit card held on file. Some "Signature" experiences, like Victoria & Albert's, have much stricter 48-hour cancellation windows and higher fees. For Park Reservations (which are still required for certain ticket types and Annual Passholders), missing a day usually doesn't cost money, but for Annual Passholders, it counts as a "strike." If you get three strikes in a 90-day period, you may be blocked from making new reservations for 30 days. For Lightning Lane or virtual queue slots, if you miss your window, the reservation simply expires and is lost; however, cast members are occasionally lenient if you arrive within a 15-minute "grace period." If you know you're going to be late, the best move in 2026 is to use the app to "Modify" the time rather than letting it go to waste.
