Yeah, I did. But I'm in the UK, where more people seem to take a year off between school and university (college).
I worked in the French Alps in a hotel as a dish pig and a nightporter. The job sucked, but it meant I got to ski most days. I loved it so much, that after two years at university, I took a year out to go and work in France again last year. Was a chalet host, just serving breakfast and dinner to guests, meaning i had all day free to ski. Stuck here in UK for one more year, before I'm back next winter. (and the one after that, and after that, and after that!!) I have two weeks off starting next week though, and i'm taking a trip to the alps, yeah!!
Do it man, its so worth it. It'll give you a great experience, and a chance to chill, after high school. You'll meet so many cool people, and make great friends for sure. Plus, obviously, its a chance to really step it up with your skiing.
