Everyone has given you interesting advice based on their experience. The great thing about a road trip is that your plans will change as you go, so be organized and be prepared for the moment when you are cruising through Utah and an urge to go to more than one ski area hits you and Adam. Driving through the Rockies tends to make you want to ski...A LOT!
On one memorable road trip, I picked up a hitchhiker in the middle of nowhere (50 miles west of Green River, Utah), and went to Salt Lake instead of home to LA. My boss didn't believe the sick calls but, skiing Snowbird and Alta with local powderhounds was worth it. If you get the urge to ski more than 1 day on the way, then the Alta/Snowbird combination is ideal. You really need a few days to find your way around the nooks and crannys of Alta.
If you recall my earlier advice about Sun Valley, do not forget who you heard it from first. About the Sun Valley snow, they are reporting the same base amounts as Vail and some other CO areas. For an advanced intermediate boarder, the terrain at SV is ideal. Natural gulleys, 3,600ft vert. non-stop GS cruisers, great glades, big back bowls for powder, high speed lifts (you only have one day, right?), and a pyramid shaped mt that eliminates long traverses to find the slope you want. It is very easy to find whatever slope suits your mood when you stand on top of Sun Valley.
Now I think I have to call a travel agent to book Sun Valley ASAP! Amex should thank you!
