we ALWAYS open the presents Christmas morning! I used to beg my parents to let me open one present on Christmas Eve before heading to my godmother's condo for her yearly party, and almost always was allowed that one present. This year, she didn't have the party, and we didn't have as many presents under the tree, so no early present for me.
My boyfriend's family opens them all on Christmas Eve... now, if he and I ever get married, we're going to have to come up with some sort of compromise!
