Call around to a few properties and speak to the GM about an extended stay rate. 
+1 to all these observations, with the possible caveat that TPS clientele is probably very location-dependent; on a two- or three-night midweek stay at the one in Manhattan Beach, for instance (2-3x/year for the past 5 or 6 years), I'd usually see 8-10 work trucks belonging to construction/utility companies (and lots of people sporting hard hats and/or tool belts) in addition to a good number of more-or-less-typical white-collar business travelers, but seldom more than one or two families with young kids or teens
