IIRC the holiday rule has been around since day one of the DDE. From allears: Certain restrictions apply during holidays and special events, please check with the restaurant when you make your reservation. Blackout dates include major holidays: Mother's Day, Easter, 4th of July, Thanksgiving Day, Christmas Eve, Christmas Day, New Year's Eve, New Year's Day.One thing, they didn't accept it on mothers day. Im not sure if that is new or not but it made sense.
