I did this tour a few years ago - solo female. I have taken RS guided tours, too. For the MyWay Alpine, I came prepared with a list of possibilities to fill my time. I was happily surprised that while I got to do things on my list, our group really jelled, and I did things I had not anticipated by hanging out with others. Maybe because it was all up to us, folks made an extra attempt to form community. At any rate, this was a convivial group. I always felt I had the option to be with others or go off on my own.
I also learned the lesson on this trip that sometime travel can be a vacation - that is when I ditched some of my list. It was much more fun to see what the day, the locations, and my tour mates offered: boar burger near Hohenschwangau, the Greek restaurant in Fuessen; an afternoon enjoying the views from Gimmelwald's Pension. It was a good group.
Of all the tours, I plan to take this one again. This time, I will walk the Lauterbrunnen valley floor trail, which is something I was unaware of during the last trip. Over Covid, I saw some lovely youtube videos walking this area in the snow. Heaven. I also want to explore, or at least reflect on, Tolkien and Lauterbrunnen when I am there.
Hotels: the typical RS mix, all fine, some in fantastic settings. I really loved the one in Chamonix - the river ran right by us, and we held an impromptu wine party on the mini-lawn. Enjoy!
