This is the OP. I just called back and was able to make a lunch reservation in Oct with a different CM.
I am very glad to have this board because otherwise I never would have known to call back again. Why are all the CM's so misinformed? On another note of misinformation, while making my Liberty Tree Tavern lunch reservation, I also tried to make one for Planet Hollywood dinner. This CM told me that Planet Hollywood does not accept the dining plan. So, because I know it does from reading this board, I was able to call back and talk to a third CM who made my Planet Hollywood reservation and confirmed that they do accept
DDP.
Without this board, many many people must be getting wrong information from CMs and missing out on many things.
