This question isn't about a reward night reservation cancellation, but it's fairly related and I didn't know where to put this:
I'm looking at booking some reward nights at an IC (not PB), but I don't know if I'll be able to go. If I book it on my own, then find out that I can't go, is it possible for me to change the name on the reservation (or add someone and have them show up only) without cancelling the reservation?
