No Brainer...
You've stayed 23 times (assuming no AX cc credits) and you don't see any value in staying 2 more times before the end of the year?
Do yourself a favor and make 2 more stays... I don't think you'll regret it. Alternatively, search the web for a big rubber foot and rig it up with a rope... hang it over the door in such a way that you can kick yourself during 2012 any time you want.
