Last time I drove cross country, I stopped at Motel 6's because of their multiple dog policies.  

Many of those looked like they had multi-family members living in two or more adjacent motel rooms on an extended-stay basis with barbecues, bicycles, lounge chairs etc. cluttering the sidewalks in front of the motel rooms.  

Looked like working people with families who couldn't find a cheap house or duplex to rent so this was their alternative. 

I can envision a couple of downsides for the a motel manager....
