DSIL and I are taking the kids to see my parents in S. Florida next week. We just now decided to go to WDW for one night. We bought the dining plan. Now I can't get and ADR for dinner on the 9th. We wanted Chef Mickey's. They are booked until 9p. The kids are young and we will have been up a long long time at that point. What do you think my chances/if any are of a walk in?
