Thank you so much for the response.
Looks like it's bit late to book the recommended hotels at this time (either sold out or too expensive at this point).
I suppose I am okay with my choices in Lucerne, Montreaux and Zurich for now.
For Interlaken area, after doing more research, I wonder if Wengen or Lauterbrunnrn might be better.
The forecast is pretty much rain at this time (May 14 ~ May 23); so, it may be muddy based on some inputs I got.
For Wengen, I have Hotel Falken and for Lauterbrunnen, Hotel Silberhorn.
Alpenruh Klum in Wengen seems to be available too (the other Alpenruh I mentioned in the original post is the one in Murren).
Once again, thank you all for your time.
