I'm travelling with my mom and she wants to see as much as possible so I do my best to make that happen. With that said, my idea right now is that on the day we leave Murren, we'll go up to Schilthorn in the morning then take the train out to Lucerne. We'll spend the rest of the day in Lucerne then take the overnight train to Salzburg. It departs at 21:54 and arrives at 07:58. Unfortunately there are a few transfers (Lucerne -> Basel -> Karlsruhe -> Munich -> Salzburg) but there's not much I can really do about that. I'm just wondering if anyone has done something similar. It looks like it'll be about $50 a person which is pretty good all things considered. I know we won't have a bed for that night but we get into Salzburg early in the morning which is what we want because we've got a rental car waiting for us and we're off to Hallstatt and hopefully Hallstein if the weather is good.
My other option is to spend the morning at Schilthorn and board the train in Lauterbrunnen at 13:32, skip Lucerne, and get to Salzburg at 22:02. I've ridden the train from Munich to Salzburg before so I know what that scenery looks like but if I'm missing some world class train ride overnight maybe I leave out Lucerne and just enjoy looking out the windows on my way to Salzburg?
Thanks in advance.
