Stayed at the Dowtntown Phoenix Sheraton for 7 nights. As a few others here, I am fairly tidy and value the points a lot more than a freshly cleaned room. I made it the whole time just fine and ended up with 6 certs supposed to be worth 500 points each. hopefully they post for an easy 3,000 points. To be safe I took a picture of them with my room key folio which included the date and room number.
