You will really like the Little Nell, it's a very nice hotel. You will probably end up skiing Aspen Mountain the most, since the gondola is about twenty feet from the hotel. It actually has the best bumps and glades in the valley.
Get out early!
They groom Copper, Spar and Ruthie's every day and they are always buffed to perfection. Then start skiing the east facing runs in the morning, Back of Bell, Walshe's and the Mine Dumps. Then follow the light to the west facing runs in the afternoon, Face of Bell, the Glades and Jackpot.
Highland's is a great ski area, with some of the steepest terrain in the valley. You just have to hike the bowl. Take some water with you and do it on a nice day.
It might be good to have an instructor with you, she can carry your skis!
Snowmass is cruiser paradise, sprinkled with a little extreme terrain. Don't go there when its windy!
Buttermilk has some of the best beginner terrain anywhere. I think you should get your wife to learn. They have great instruction and it will keep her out of the stores, thereby saving you some real money!
It's really hard to find a bad meal in Aspen, if a restaurant isn't good, it doesn't last long in this town. I like Campo de Fiori, Blue Maze, Taka Sushi, Jimmy's and Cashe Cashe. I would also recommend the cabaret show at the Crystal Palace. The food is only ok, but the show is outstanding!
