I did an Edelweiss tour at the start of July '16. I liked the mountains (mostly). The group split into tiny cliques and generally there was no group cohesion. One guide was intent on breaking the sound barrier, the other was stuck with the slow and the scary. Overall, a hell freezes over first experience. This past summer ('17) I rented a BMW K1600GT and went pass hunting. The passes with the serious "do or die" hairpins were, on the K, near drops waiting to happen - no bottom end guts and no way to wind the motor up even 1st. The '16 trip was on a '16 BMW R1200 RT. Once I learned to "ride it like I hate it", it worked out well enough (see avatar). NTL, by the end of the week I really did hate the RT.
Last summer, when I was looking into rentals, I looked for FJR's. If anyone rents them, I didn't find them. And I saw very few on the road.
In general, tours talk about 3-4 star hotels a lot. The stars aren't Michelin, Tripadvisor, Google, or even AAA stars. They're a measure of the hotel's extras - pool, steam room, gym, etc. At the end of a long day or lots of passes, time in a gym is highly unlikely. Steam? Maybe. NTL, all those stars are folded into the bill. I'm just sayin'...
There's no point in trying to see or ride it all. Just not gonna happen. I scheduled some amazingly long days (150 - 175 miles is much longer than it seems! DAMHIK) and, by the end of most days I was seriously knackered and PO'ed I'd had to cut things short. If I'd had any sense, I would have, as an example, stayed near Andermatt (google same) and operated from there. Interestingly, St. Gotthard, Nufen, Grimsel, Susten passes were surprisingly easy. Furkapass (can't get back to Andermatt from the west without it) looks like another friendly ride. And then you reach the descent back to Andermatt.
The big take-away? Passes take far longer than expected. There's a lot to do along the way. Include time to stop and smell the roses. This is not a place for Ironbutt riding.

"We booked...", "I stayed..." short version, my wife doesn't ride. She, her sister and brother, went off on their own trip while I went off riding. We met up during the week.
