TownePlace Suites (Marriott) is geographically the closest (by about 7 minutes). And there are several restaurants, three grocery stores, and a sizable mall just across the street (within 100 yards). If you don’t have a car, TownePlace Suites is the more convenient of the two.
Rates that we’ve negotiated at TownePlace are slightly more than the AC, with the AC being noticeably nicer than TownePlace, but still very decent all-around. TownePlace Suites is my 2nd favorite option.
