I've already got three stays accounted for in the next 3 months. Will this work to get Marriott and Starwood Platinum? Also, is it worth it for me to spend on six additional stays with Marriott in order to get platinum Starwood. What I mean is, what are the chances of me being upgraded to a suite at the Bristol being a Starwood Platinum? Thank you.
