This is where being a good FTer has a lot of value!
As an example, I recently booked a stay at The Cosmopolitan in a Terrace Suite that was selling for about $850/night inclusive of taxes. I was able to book the same room with 40,000 points + $100 (a value of about $0.018/point, which is on the high side for marriott rewards points). However, I paid cash for another night during that stay which was significantly less expensive.
Most redemption opportunities I see are usually around half a cent per point…
