Christmas gift second thought

[luv that cruise]

I'm curious for a few of you who seem to know a lot more about DCL than I do... Another thread mentioned "name changes" on reservations. I thought there was something about the "lead" on the reservation not being able to change? A friend was given a february cruise as a Christmas gift and her heart is just not into it. A group of us going but we each have our own room. I could find another friend who would like to go and would gladly pay a name change fee. She is grinning and bearing it but if there is an "out" I feel like I should at least share the option to her. Please don't judge. A well intentioned gift but the timing may not be right. My prediction is she will go and be glad for the time away but just trying to be a good friend and tell her if there are options.
