Replying to Where to Ski in Norway??

I'm gonna be in Bergen on a family trip in Jan and want to get one day of skiing in. Gotta check off that bucket list item of skiing in Europe! Anyway, I'm not sure where to go... Hemsedal seems like the best bet. Geilo and Voss are closer. I'd really like to pick the place with the best off-piste terrain that doesn't require a guide or expert knowledge of the area. I don't care about the park at all - been skiing CO my whole life. Any suggestions??
