Since so many Swiss experiences are weather-dependent, we're trying to be flexible about what days to do things. So, for example, we'd like to decide the day before whether to buy Silver Round Trip tickets for Mt Pilatus. The website says "print@home - The ordered tickets are available for download in a PDF document to be printed by yourself." Do we actually need to print these out (in which case we'll need our hotel's help), or can ALL the various modes of transportation (train, cogwheel train, cableway, gondola life, bus) just scan the PDF from my iPhone?
Thank you!
