My question was rather: what would you recommend is worth doing in southern Poland in the winter that's not skiiing and not Krakow?
I wouldnt recommend skiing in Poland in the first place, its not the best area to ski/snowboard, in Zakopane the cues are an absolute nightmare and most of the other resorts can be done from top to bottom in about 30 seconds.
If i were you id look for a nice peacefull log cabin out in the woods preferably near a lake, take entertainment with you and stoke up that fire. Winter walks and fishing in the day and in the evenings cosy nights in around the fire with a bottle of wine. Cities are boring as hell in my opinion they are all the same.
