Grindelwald is a pretty village take a train ride up the Jungfrau watch the climbers tackling the Eiger
or stay in Zermatt with a train ride up the Gornergrat and gaze at the Matterhorn.
Davos, Klosters, St.Moritz, Lucerne are all worth a visit. There are package holidays available on The Glacier Express

The last time I went up the Jungfraubahn (railway) it cost over 200 swiss Francs and that was maybe 10 years ago so you would probably need to take out a mortgage to buy a ticket.
As others have said Switzerland is very expensive but a lovely country with awesome views.
