Anyone ever use Limo's Through Disney?

[gymnuts]

When I booked my trip I also added Limo transfers. Yesterday I called to give the info on our arriving flight and our departing flight. For some reason the CM seemed a bit confused. She said something like " Oh yeah they would need to know when to pick you up". Have any of you ever booked your limo through Disney? Did you call the day before and make sure they would be there? I have this strange feeling we might get there and our limo won't. Any help would be greatly appreciated.
