BA Fan, with the winter specials going on now, it shouldn't cost much to do a "mattress run" at an inexpensive Fairfield or Towne Place Suites property. Given that you've got almost seven weeks left (and some darn good weekend offers going on), you should easily be able to score the remaining nights you need before the end of the year.

Give it some thought. I'm sure many of us here can offer recommendations.
