figment the only way you are going to get a reliable answer is to call the hotel and ask for the buffet manager and ask that question. Even doing that, there is a chance you will hear that its too early to give an answer about Christmas eve, and they haven't decided yet. Even if someone says that last year they accepted it on Christmas eve, that might not be the case this year. Getting "helpful" answers from well meaning people who really don't have any authoritative answer on a message board will only frustrate you when you find they are wrong.
