Lots of runs and lifts, good weather, friendly staff
Some runs get crowded
Love, Love, Love Breckenridge... I would say its tied for first with Copper Mountain (in my opinion). There are a ton of lifts and runs, so you don't normally have much of a wait. Peak 9 has excellent runs for those who are new and/or prefer extra space on your run. Some of the runs on Peak 8, because of the way it funnels into the lodge, can get kind-of crowded. But, Breck offers many options for every level skier/boarder. Overall, amazing runs, great snow (not icy like Keystone tends to be), and excellent locations for food/taking a break.
