MrsW Is this for a one night stay or a more-night Stay? I am asking, because I had this at my booking at the HIX Denver as well (around 16.333 points per night). Cash and points rate for my four night stay were very differnet. Howadays the average amount per night is shown which is the whole amount per stay divided through the number of nights. Depening if you have an odd or even number of nights this could be the result.
You shold be able to see how much points are required for each night.
If this is indeed for a one night stay, than it is very odd.
