it depends. what kind of area are you wanting to go? busy city, not so busy, rural areas close, can you speak diff languages, that sorta stuff. prob with skiing is it'l only be northern hemisphere obviously, so ur kinda limited to europe/some asia. maybe you could do india/turkey like those random updates of mtns in places we dont even know exist. but europe is prolly ur best bet. also depends on how much time you have.
i went to france with my school this past april as part of a 2 week exchange and it was cool. i got to live on a ski resort for a week with a chef. it was a really rural area. 100 people in the town where the resort is and it was huuuuuge. they had a cheese factory near by too. but then not too far away was a more populated town and nice vacationish areas. the next week we went to paris and stayed in a hostel in the city. it was cool cause we got to see a lot of diff things. if ur into seeing art and a lot of history, esp religious historical stuff then france was real good for that. even if ur not(like me) its still pretty cool to see all this stuff that you've been told about before. and its fun to mess with the gypsies.
