I’ve found the Key Access offers to be solid. You access them at the bottom of the “redeem” page by clicking the “unlock your secret rates” button.

They are cash + a small amount of points (like 500 per night). I have found that the pricing is sometimes better than they indicate on the site when you look at the available properties so it’s worth trying them to see what the final pricing looks like.

One note is that they don’t earn points. Not a big deal though, I was able to book some nice properties at a substantial discount.
