Usually, with a points and cash rate (code 51440), your only choice is a standard room. Here, however, on some nights the Grand Executive Suite shows up as a choice. The suite has “500 to 600 sq ft of space, a workspace with an ergonomic chair, a marble shower, and a queen sofa bed” and club access. With tax, it comes to $175, and you can cancel up to 48 hours before without penalty.
Note: I see availability sporadically from present right through October 2018. In fact, I booked a night for my birthday next October.
