I just booked a room for later this year and for the very first time that I've noticed within the booking confirmation once you make the reservation there is a box asking if you would like to guarantee an upgrade and a specific room type noted along with the amount.  I've seen this with Hilton, but not with Marriott previously. 

Has anyone else noticed this and if so how long has it been showing up?
