Need help with finetuning my 20 day Swiss+Italy itinerary

Yeah. I guess even if I go from Zurich, the whole Bern-Interlaken-Lauterbrunnen-Wengen route will be have to be taken regardless of anything which is why I thought to include apenzell in the itinerary. Thanks for the detailed response though.

And as per you, does the remaining itinerary seem ok to you? Or would you suggest any changes?

I would put Lugano and Morcote in the same southbound trip as Cinque Terre—-either on the way down or the way back. For example, on the 18th, instead of going all the way from Cinque Terre to Zurich, you take the train from Cinque Terre to Milan to Lugan, a short distance beyond Milan. Then after your time there, continues to Zurich on the train from Lugano.

My concern would be that you are spending so much time in transit that you're not actually being anywhere. Like your first three days are mostly traveling not seeing much - an evening and a morning in Paris while dead tired from travel is nothing. Saving money on lodging by staying in Zurich is fine, but its costing you much more in your transportation costs. And your precious vacation time.

So based on suggestions, we are now planning to skip Paris all together(really had to convince my wife for this:p) and maybe base our selves in Milan for the first few days and explore nearby areas and then head off to Switzerland and continue with the above mentioned itinerary. And maybe skip Lugano altogether. How does that sound now?

I agree with the Other posters, you are spending too much of your vacation on trains and transiting. How about starting by taking out Zermatt, as you'll actually be in the Alps in the Berner Oberland. Slow down. Also, the Paris segment should probably also be saved for the next trip. August is hot in Europe, so why deal with Paris in the heat, when you can spend more time in the mountains?
Good luck and safe travels!

As I told you on TripAdvisor, radically skip certain bases, to reduce complexity and costs. Skip Appenzell & Aescher, skip Paris, focus on Switzerland and Italy with two bases each at max.

If you have family in Zurich, there is always the possibility to come back to Switzerland; next time you may be combine France & Switzerland.

Tell your wife that August is the worst time to see Paris—too hot, many of the locals are away on vacation. It will be more enjoyable at another time.

Milan will also be hot, and expensive. Instead of “basing” there, why not spend 2-3 nights on a nearby lake (Lake Como), then move down to Cinque Terre. On your way back to Switzerland, break up the journey with an overnight in or 2 in Lugano or Morcote. There are direct trains from Lugano to Zurich, making the journey in under 2 hours. Spend your time with family there, then move on to Appenzell, etc.

The timing of the Italy part would probably work out to have you back in Zurich on the 20th, so you could spend Sunday the 21st exploring Zurich with your family.

If you're in Milan, would you consider going to Lake Como for a few nights, then to Tirana, where you can catch the Bernini Express scenic regional trains ( regional trains are covered by the STP, and no reservations needed), thru to Pontressina ( more scenic than nearby St. Moritz.)
This allows you to experience the beauty of Switzerland while transiting.
Safe travels!

I agree with Stan and Pat. Zermatt can be fun IF you can allocate enough time to be there, as often the Matterhorn is covered in clouds. You'd hate to spend all that time getting there, and then not see the Matterhorn. As for Paris, if you are persuaded to go there, you have to reserve seats on the bullet trains between Zurich and Paris. (All other Swiss trains, no worries about reservations.) See www.seat61.com for THE definitive resource on trains in Europe.

Also, before you get to Wengen, check out the hikes at https://lauterbrunnenhiking.wordpress.com/ That will help you decide if you want to get a pass or not. (General rule of thumb, if you see you'll be taking a LOT of cable cars and trains, it's probably worth it. Also don't purchase a pass way ahead of time--you may later find it is raining that whole week. Buy it first day you'll use it.) In any case, the MUST do trail for you is to take the cable car from Wengen up to Mannlichen then take the 90 min hike down to Kleine Scheidegg. It is our favorite.
