Advice Needed on Switzerland Rail Pass

Hi! We are a couple planning to travel on our own in Bern, Interlaken, Luzern with excursions to Lake Luzern and Jungfraujoch. Would be helpful if anyone could advice us on a few issues. We are travelling on a tight budget.

Our itinerary would include train from Geneva to Bern(we will be staying in Geneva first and our flight back home is from Geneva) and a three nights stay in Bern. From Bern, we would be travelling daily to many destinations - to Interlaken and then 'mountain train' to Jungfraujoch and then back to Bern; Bern to Luzern with perhaps boat rides in Lake Lucerne(if that's possible) and then back to Bern. Finally a return train to Geneva from Bern.

A few questions needing advice:
1.)Would it be more advisable to get a 4-day Swiss Pass than to purchase the tickets separately with such itinerary?
2.)Does the Swiss Pass also cover tram rides?
3.)The 'mountain rail' to Jungfraujoch - is that 'free' with the Swiss Pass or do we still have to purchase separate tickets for this?
4.)I wonder if it's practical to have an excursion from Luzern to Mt. Titlis or Mt. Pilatus on just a day-trip to Luzern from Bern?
5.)I have difficulty purchasing detailed maps(with street names; train, bus and tram stations/stops; hotels and restaurants) of Geneva, Bern and Luzern in my country and trying to find such maps in the internet had not been fruiful. Any suggestions of websites with such maps?
6.)We were thinking of purchasing the Swiss Pass from a company in this website:- http://rail.myswitzerland.com/ . The company has a special offer for Swiss Pass of 4 days: http://rail.myswitzerland.com/produkttexte.php?passid=1 . A few questions(as we had some not too good experience with online purchase/booking):-
a.) Is it advisable to purchase the pass from this company?(i.e. has anyone purchased the pass from this company to ensure that it's not some scam/bogus site?)
b.) We live in the Far East - will it be a problem for the Pass to be delivered to us should we purchase them?

Would be grateful if anyone can help us with these questions. Thank you!

Hi wanderlust, and welcome to our website,

As for your questions:

1. Yes, a pass would be more economical and convenient.
2. & 3. Yes, trams are free. The Jungfrau trip is free to Wengen and 25% off from there on. Our Swiss Pass page allows you to download a network map to see such details for yourself.
4. I'm not sure what you mean. You can travel to the valley stations of those mountains for free and get your discounted ticket to the top there (assuming you have a Swiss Pass).
5. Our hotel pages have maps you may find convenient to prepare your trip. As for paper maps, you can take a look at mapsworldwide.com. Maps will be available locally as well.
6. That offer is available on our site as well. You can find it here. In order to find a reseller, you can best visit our Swiss Pass page I linked to above. Fill out your country, preferred pass and number of travelers on the right, and all appropriate options will be displayed. It includes details such as shipping amounts and delivery times. This saves you from a lot of searching for resellers. We've only listed trusted resellers we work with for years.

I hope this helps. Enjoy your stay!
