I also agree that it's a pretty good price. All-in, it's $62/day and I've paid nearly that for full size at some places. My only recommendations would be to try the other AWD #s listed at the top of this forum & on other pages, along with coupons from Avis.com and other sources. It's nice to get airline miles, but not all off-airport locations will give miles so you might want to check to be sure you actually accrue miles at this station.
As for coupons,
AVIS.com lists a few, including one for like $25 off at off-airports. However, it expires at the end of September. I'd keep watching there to see if they add any new coupons.
Have fun!
