If the summer glacier is not your cup of tea:
Different language, culture, avalanche skills, fresh powder, and silly Argentinean tourists is matching outfits, (don't worry, they don't even make it up the hill). Mind you, I would not go there to ski park. But if you just turned 18, you can party, drink, and gamble until 5am. Then go ride a couple nice, untouched lines a few hours later.
