Don't know if it's open Xmas eve but pretty sure you have to book tour same day. Just go to visitors center a block from his birth home and across the street from Ebenezer Baptist church. Have your name put on the tour list and they will give you a tour time. Your group will be given a ticket and you all go to the gift shop nect door to his home where a ranger will meet you and conduct the tour. You can't take photos inside the home.
It is closed Christmas eve and day. However the grounds around the King Center and Birth Home are available for viewing. TheKingCenter.org
