I’ll be going on a very short visit to Switzerland this 1st week of November & will stay mainly within the vicinity of the University of Fribourg. What is the nearest mountain or ski resort that I could visit where I can have a good experience of the Swiss alps?

Hello,
I’ve heard that switzerland is an expensive place to ski. I’m going in January and was wondering what kind of costs to prepare for?
Are there any good value ski rental outlets?
Can i get English ski lessons midweek?
Any good restraunts or hetels i should check up?
