Its too much trouble and tooooooooo costly too. By booking on orbitz.com (alamo.com now quotes the same rate) I gotta a full size car at SEA Jan 13-20 for $128 w/ unlim miles. Using the 4 most recent "discount" codes listed in this forum, I got rates of $133.72-$228. My corporate rate would be $159 if I used it w/ 150 mi/day.
