I did on several occasions.

It was also a couple years ago for me - I was checked into a Residence Inn for a month but flew out on one-night trips to visit clients in other cities. We would stay in a Marriott and get night/point credit.

It really wasn't wasteful for us because that particular Residence Inn was giving us sweet rates for the one-month stay. If we had checked out more frequently, we wouldn't have gotten that same rate.
