Do you have to play off Mlife corporate offers like you do with host booked trips? I know with a host booked trip, if you receive a complimentary upgrade at check-in to a more expensive room, that becomes factored into the comp amount that you are expected to play off and if you don't, the host will probably not be too keen on helping you out in the future. Does it work the same way with a corporate offer trips? Am I expected to play a higher amount for that trip because I was technically "comped more" than what corporate originally was willing to spend on me? Will my offers for Winter dwindle if my play doesn't justify the "complimentary upgrade"?
