One thing worth noting in those point "prices" is that the per-night point cost decreases with longer stays. So, for example, a four-night stay at a given Marriott property will cost less per night
(in points) than a one-night stay will.
So if the points aren't burning a hole in your pocket, it can be worth it to save them for a while. But if you're trying to spend them before they expire, or if you don't expect to be earning any more for the foreseeable future, you've certainly come to the right place.
