well thanks for replying on xmas day:
based on that, I got a flight/car orbitz package - basic 2WD car is $221 extra (all-inclusive) for 8 days; I probably could have found cheaper messing around with the minute-minute fluctuations on orbitz, but I don't have the patience today and all I care about is if the car has a fold down seat that will fit skis and it does. It's only $130 more than those shuttles; maybe I'll find some use for the car. I'm getting into SLC midmorn so I can ski a half-day upon arrival before condo check-in, and also a half day before my late flight out on the last day- sort of use the car as a ski-locker (I can rationalize anything). I'll see how this all goes.
I just hope there isn't another post later on saying I need a Humvee, shovel, snow-shoes, or crampons and rope (like you would going to Kirkwood, today).
