While our fellow retirees are heading to Florida for the winter, we are considering a Great Railway Tour of Switzerland in January. Quite the opposite strategy than most New Englanders but we wanted to see the Alps with snow and in its grandeur. But I want to avoid a big mistake if it is just too cold or the weather is too aggressive. The train seems like a somewhat risk-free form of travel and the Glacier Express Tour looks like just what we are looking for. Any experiences out there with these tours or The Alps in winter? Thank you.
