We visited Switzerland last year and are returning this year for my 60th birthday. I love trains and would like to ride the regional trains so that we can get off where ever we choose. The issue with this is luggage as we will be in Europe for 21 days total. The wife will not pack light so we will have two big suitcases. What I'm considering is establishing a base in a relatively cheap AirBNB and travel out. We have a week to 10 days to explore. We've did Luzern, Lauterbrunnen, and Zurich last year, so not much interest in those areas.
I'm thinking of basing in Andermatt to see Zermatt, Lugano and St Moritz. Would spend a night or two in each. I know this sounds a bit ridiculous, but the money isn't really an issue in exchange for the convenience. We really don't want to drag luggage around and could pack a small hiking backpack for the overnights.
Thanks for any thoughts or alternate suggestions.
