Marriott has always seemed to be the really focused on standardization and they were probably able to negotiate better terms bringing all the Starwood properties on board. I started doing some digging last week when I randomly had a bottle of Aquafina in my room amongst the Dasani and found a report that Marriott moved to Pepsi in the early 90s when Coke refused to give the (then) struggling company a $100 million loan.
