I don't mean to alarm anyone, but I called yesterday about my missing Le Cellier reservations. I was lucky to get two--a dinner one for my arrival day, and a lunch one later in the week in case our plane was late and we somehow missed our arrival day ADR.
The CM (Toby) was very helpful, confirmed all of my other reservations and was able to find my arrival day Le Cellier ADR. However, she was not able to find the second one! She checked under my name, phone number, resort reservation number and even went to Le Cellier's ADR list for that day and checked the timeslots around the time our reservation was and could not find anything.
I'm not that concerned because my plane is landing at 11:30AM and my ADR is for around 5:00 (and we're renting a car), so we will likely have no problem making our arrival day ADR. That said, I wonder what would happen if I actually showed up with my confirmation for that missing lunch ADR?

Surely not everyone is as anal-retentive as us DISers to continually confirm (and tweak) reservations.
