Is everyone aware that the use of points often excludes vacation club locations and suites? I have accumulated a vast amount of points over the last year and I am surprised and VERY disappointed that they don't do me much good for a family of five looking to vacation in comfortable accommodations.
You can always cash in your points for a Marriott Gift Card or Gift Cheque. Sometimes I will do that when I can't use points. The nice thing about using the Gift Cards/Cheques is that your Marriott rewards account will still get credited for the night and you will also still earn points for your stay.
