5 day trip to Switzerland

Hi , I am really amazed to find this forum.
I am planning for a honeymoon trip to switzerland in the second half of April. I am planning to go to interlaken, lucerne, mt Titlis , Jungfraujoch . Some friend of mine has said that public transport is very costly there. Can someone pls let me know how should i minimize my travelling expenses. i.e airport to hotel to the sites etc. what will be the most suitable pass for me.
thanks .

thanks moderator.. I saw the link. I think I can go for 2 for 1 rail pass for 4 days .. that will be sufficient for me .. But can I use this pass for travel from airport to my hotel in zurich or will I have to get another pass. Please let me know ..

Hello amitbansal0810. Yes, the Swiss Saver Pass will cover traveling from the airport to your hotel as well (as urban transportation in larger towns is included). The validity network map we link to from the Swiss Pass page provides all details.
