Breckenridge has a really really kick ass park and has been on top of the big air game since people started pushing snow around with groomers. Its great for intermediates, beginners and experts; in fact its a pretty rocking place to be for all abilities of skier. The village is really really high so take your oxygen mask... I'm not kidding! In fact, its so high that I wouldn't recommend this place for the unfit, because a few minutes of exersion here will really do you in if you aint ready for it. Because of the height, Breck and the other resorts nearby (Keystone for example), all at similar altitude, are amongst the heigest resorts in the world and are a pretty sure thing for snow.
The village offers some pretty decent partying at night and some awesome places to stay and eat. It comes at a reasonably hefty price though, so be sure to have a full wallet before you visit. I found that the "Underworld" club was particularly good for good dancing music and a freindly vibe.
