I have an upcoming seven-night stay with my wife and two kids booked on points and upgraded to a Grand Suite with a TSU. I was considering cancelling that reservation, booking a ~$240/night cash rate, and upgrading to a premium suite with 9,000 points/night. That would put us into the Grand Executive View Suite. Has anybody stayed in both room types? Is the premium suite THAT much better? It sure looks to be in the photos. I'm tempted, but it also seems a shame to forego "maximizing" a TSU on a seven-night stay.
