If you truly want something different, then I'd suggest trying Jackson. It is an hour flight from Denver. You've got options -- stay in town where there is more nightlife and take the shuttle to Teton Village, or stay at the Village, and hang out at the Moose, Alpenhof, or take the shuttle into town for an evening out.
JH has several things going for it. First, it has, amazingly, quite a few groomers that range from Colorado mild to pretty steep, it has terrain that will challenge you even on the groomers, the vertical is amazing, the scenery too, and you cannot find the variety and options of terrain in Colorado that you will find in Jackson. Because of flight times, you should be able to get 3 full days of skiing and 2 half days, which will maximize your skiing. And the first half day is free when you present your boarding pass.
You have a great deal of options on lodging as well. If you want cheap but clean (and funky) lodging, the Hostel X is perfectly adequate at about $60/night. And it is 100 yards from the lift. The Inn is a slight bit more upscale, but still affordable at about $150/night. There are a number of options in town that are in the 50-$100/night range. Last year I stayed at the Snake river Lodge (pretty swanky) for $150 a night (found it on travelocity). You can pull out all the stops and stay at the 4 seasons as well, although it will set you back $500+ (less than the St. Regis or the Little Nell in Aspen, though).
Restaurants are plentiful and their quality varies both in the Village and in town. But there are many choices, and locals can guide you to the best quality for money.
