I booked the JW Marriott in London in January for an August stay for 71K pts/night. Not long after I made my reservation, the price shot up to 76-80K pts/night. It didn't come back down again until today. It is now 65K pts/night. I have to decide if I prefer the Sheraton Park Lane which I was able to snag at 57K pts or the JW at 65K pts.
I have to admit I am very surprised after the increases we saw last week. Sheraton on the other hand, is now 77K pts/night,
