Sometimes, even if you are late, you can still get in! This past week, we had gone back to the resort mid day, and had a 4:10 ADR at LTT. To make a long story short, I looked at my watch wrong, and thought it was 3:05, but it was really 4:05!! I tried calling the dining line on the way back to MK, and when I finally got through, they said the could not cancel it since it was already 4:15 at that point, but to just go to the restaurant anyway since there were no more reservations for that day. We finally got there about 4:50 and were seated within 10 minutes!! I was very apologetic, and they seemed very understanding. I know this might not be the case all of the time, but I guess you never know!
