Okay I have tried but I am confused:
1. I am going from Bellagio, Italy to Luzern, Switzerland. I know I will have to boat to Varenna and train to Milan Central. I can't get the ticket from Varenna to Milan in advance (I know I need to get this little ticket at a travel agent in Bellagio) but I would like to pre-book my ticket from Milan to Luzern in advance. I can't seem to get this on the Italian trenitalia web site. So maybe you can't book tickets across the border? I heard it was cheaper to book on trenitalia than rail Europe? If I can't get this ticket on Trenitalia then is Rail Europe the only option.
I want to travel from Luzern to the Lauterbrunnen Valley weather permitting and I only have a two day window to do this at the end of July. Will this trip book up? Do you think I need to make an advance reservation. I normally do everything in advance, but it sounds like this is a wasted trip if the weather is not cooperating.
I want to travel from Luzern to Paris by train. Does the Swiss rail pass cover this trip? I have to connect, so I am not sure about the last leg over the border. Also will the Swiss half fare card cover this? If not and I just make an advance point to point reservation is Rail Europe the only place to purchase this ticket?
Thank you for any help. It is so confusing trying to figure out all the options.
