I know the phone lines open at 7:00 a.m. EST. I don't know when they close. If you are trying to get the Castle meal, if you don't succeed one day, call every day till you get the time you like. They open only a few time slots a day. I called like 150 days out and got a noon ADR, but turned it down, we decided to eat at Crystal Palace. Our dd is 17 and her friend is 16 and we didn't like the menu selections.
