Planning a 10 day trip covering Paris and Switzerland. Want to know how the select pass that covers 4 countries works and if it is a good option for 2 countries as well.
First of all, a pass is rarely a good deal these days. However, one major exception is Switzerland - but I mean a pass for just Switzerland, not a multi-country pass.
If your only ride in France is to get from Paris to Switzerland, you'll do MUCH better buying an advance, discounted ticket for that one ride. In addition to being cheaper, it will be easier. That's because those trains have limited seats for passholders, so you have to get the seat reservation when you buy the pass to avoid being shut out. At that point, you can just get the discount ticket.
To figure out what pass to get for Switzerland, you need to list your itinerary, your definite and possible train rides, how many of you there are, ages of the travelers (are there any children), etc. Swiss pass options can get complicated, so if you want help, we need to know as many specifics as possible.
