Courchevel is pretty nice, I did a season there a while back and while the snow wasn't amazing at the time it's a moderately acceptable place to live for a bit. Part of the Three Valleys network, meaning you effectively have 600km of runs to play with, with a majority of the runs green/blue and some relatively easy black runs.You either stay at 1850, which is the most built up, has the most bars and arguably the best nightlife. 1850 is convieniently placed next to the ski lift to the top of the mountain. However the downside is that it's the most expensive of the 3 towns that make up the Courchevel Resort.Stay in 1650, mid price range, chair lift to 1850. A couple of bars most of which will be populated by season workers.Stay at 1300, lowest prices in terms of accomodation. A gondola to 1650. 2 bars which are pretty okay, don't miss the weekly highlight of a covers band! Mostly filled with season workers. Buses to 1650-1850 until the later hours for apres ski.I'm not 100% on the legislature regarding the drinking ages there, but I think as long as you aren't a toddler they will take your money and give you drinks. Other than that, you could just watch the snow reports and just get a last minute week wherever the snow is good.
