My wife and her sister are going for a Vegas weekend and want to go to the spa. They will be staying at the LV Hilton, but could go to any spa. Do you know if there are any programs where I can turn in points for spa treatments? I have plenty of Marriott, Priority Club, Hilton, AA, or UA points. I did see that I could turn in 40k HHonor points for $100 in chips which then could be used for the spa, but I think that is a really poor use of the points!
