Sims don't do snowboarding and skiing club activities

Have you tried to add spa/onsen activities as banned for club members? Maybe that will keep them from using the onsen, and more interested in using the slopes.
I once had a cafe where both a gamer club and a painting club had their hangout. All of them were constantly on the computers. After I banned using the computer for the painting club, they finally took interest in the easels.
