Has something changed with the timeframe for points advance? My understanding is that you needed to have the points by 14 days in advance. I'm trying to make a reservation for about 3 weeks out, but am short a few points (which will be in my account by 14 days before), but it's not letting me do the booking, and saying I need to buy the additional points. I only have one other points advance reservation for one night, so I'm not "maxed out" with points advance resos. Has something changed here?
