Wow! I was thinking of the same strategy for a ski trip in March also: Sun p-up,Sat rtr, using that code, but going one class up just in case for more room as they'll be 4 of us. It looks like that location and the dwntwn Marriott are the only 2 open on Sunday; maybe the Marriott runs a shuttle out there that u might be able to catch; we're planning on having somebody local pick us up as I can't see paying up to 100$ extra at a/port. Ironically, Avis has neighborhood locations also with better rates but there are blackout dates around time we want the car.
