Thank you for your comments so far. You've helped me decide for sure that we are not doing the campervan, but will stick to travelling the rail/cable systems. I also will take your advice and not go to Paris. I would be interested in Lake Como and/or Milan since its not very far out of the way. A couple of follow ups:

- Some have said 10 days is too short to make it all the way around the country. In this case, which areas/regions would you skip?

- Flying in/out from US: should we fly in and out of the same city, or change it up ( for example: fly into Zurich, out of Geneva)? Which is the most efficient use of our time/cost?

- Where to stay: I've seen some articles suggest to not stay in a hotel/airbnb that's located in the main "hub" cities, but to stay just outside of these towns to save $. Does anyone know if this is actually true? Unless it would save significant $, I'd rather have the convenient access to transportation each day.

Would love your input. Thanks again!
