See if you can negotiate a monthly rate. I've had a case where the monthly rate (over 7 nights) was just about the same as the daily rate (extrapolated over 7 nights). The hotel wouldn't really budge on the nightly rate but they were happy to budge on the monthly rate.

I got to keep my same room for a couple of months. True, I lost 500 points every time I didn't check in but that was well worth the convenience of bypassing the check in desk every Monday evening.
