Not to be a naysayer, but if Disney does they correctly, they wouldn't be accepting ANY reasons or excuses for missing an ADR. Not for anyone, not at anytime. Once word got out that all you had to say was someone in your party became ill, everyone would use that excuse. Likewise, if your flight was delayed coming in or Disney transportation broke down, the whole policy would be moot. Also, Disney can't ask for a doctor's note; the hassle alone, not to mention the legal ramifications would be a logistical disaster. The bottom line is, ADRs are not a necessity. Yes, we all know they are at certain times of the year, but you don't HAVE TO make them. You can always try as a walk-in if you're not sure you can make it.
Some people haven't noticed this, but in the past week alone, when using the online ADR system, a very long disclaimer (which used to be for CC-held ADRs only) has been added to appear on ALL ADRs. This disclaimer has actually been on the online site since it became available, however it wasn't appearing on the confirmation page or the confirmation e-mails until just this past week. This ADR was for Sci-Fi Dine-In, a (1) credit TS @ DHS:
-Transportation Time: Allow up to 1.5 hours to travel to your destination when traveling within Walt Disney World property.
- Most Walt Disney World Resort table-service restaurants that accept advance reservations can accommodate Kosher needs if requested at least 24 hours in advance by calling (407) WDW-DINE or (407) 939-3463. Guests under age 18 must have parent or guardian permission to call. A credit card is required to guarantee this meal; the full price of ordered meals will be charged if you cancel within one day of the reservation or are a "no show" for the reservation. At family-style or buffet locations, you will only receive one meal; does not include all-you-care-to-eat. You will be charged the regular buffet or all-you-care-to-eat price.
They're covering their tails by telling you to allow for 1.5 hours of travel time, as well as that a CC (maybe not now, but soon) will be required. I didn't have to put down a CC to make this ADR. However, a new box appeared stating that $0 payment had been made -- a box that has never appeared alongside this type of ADR before.
Something is happening.
