We got a 6-day first class Swiss travel pass and it was wonderful! An email with the QR code was sent a couple days ahead and we rode in luxury in first class cars, often with very few people in them and had access to so much besides the trains! I found the prices on this site to be less than prices on other sites I checked.

The Swiss Travel Pass saved a ton of $, valuable time and the flexibility that it offers is everything!!! You can hop in and out any means of transportation. You missed a train? No problem, just hop on the next one. I used it on several museums as well. It also gave me great discounts, 25 to 50%, on mountain trains and gondolas. It's truly a no brainer! If you are traveling with family and plan on going from city to city with luggage, I recommend you get the first class tickets, simply because during peak times you'll be hauling your luggage through the wagons to find a seat for all. First class is quieter also. I found this during the first week I traveled with my family. Second class wasn't an issue at all the second week when traveling solo. It's not a huge deal, but for my son it would have been better to just get in the train and seat. If you plan on seeing a lot of what Switzerland has to offer JUST BUY THE PASS!

Excellent option. I bought the three-day pass and it's wonderful because you forget to buy tickets every time you go to use a transport. Works Perfect on all transport services within Switzerland including most cable cars. It is very worthwhile if you plan to know places around where you stay. But beware, if you are going to be alone in a city, it is not worth it because the hotels give you the benefit of having free public transport close to the area. So if you just want to get to know the city and you don't plan to go to the mountains or other towns, it may not be as useful to you.
