Do you know how to search for available Money and Points stays? If not:

Make sure you are logged into the HHonors web-site.

From the reservation search screen, make sure to "tick" the box for flexible dates and also ticking the box "use HHonors Points."

This will bring up a two-week calendar view that will allow you to search for available dates. You will need to select Money and Points from the drop-down menu off to the right-hand side when you're on this two-week view.

Good luck. ^
