Many hotels are owned by a "group" that may own, say, a dozen Best Westerns. That group may contract with one MSC for their shops, while another group contracts with a different MSC for their shops. You will begin to notice when you register at an hotel that there is often a plaque on the wall, stating the name of the "group" that onws that particular franchise location.
So, Steve is right on the money with suggesting that hotel shoopers need to be signed up with just about every MSC around to find optimal hotel shops. AND, those hotel clients do change MSCs!
BTW, with the rewards-linked credit card and a big extra points promotion, I was able to turn a 2 night stay at the flagship Hilton in Manhattan into three free nights at a very nice mid-level sister hotel, with free parking, breakfast and wifi. So, be sure o get the rewards club AND the matching credit card to make the most of those free nights. (With no reports!)
