Switzerland Itinerary??

You don't need to sleep in Zurich the night before you flight unless your flight is very early or you want to see Zurich. Bern is linked to the Zurich airport by rail and it only takes about 70 minutes to get there. Frequent departures.

Other than that, the itinerary looks fine. Personally, I would add a day to Murren/Wengen and deduct it from Montreux.

Thank you, i actually wrote it wrong. We are 3 nights in murren and 2 in Montreux.
Do you think it’s worth staying in Zurich to see the city? I still have one more night to add somewhere, I have heard Appenzell, but I’m afraid it may be too far out-of-the-way. Would you consider two nights in Bern? What about Zermatt? Or make Zetmatt a day trip?
Thank you so much.

We spent two nights in Zurich and found enough to enjoy it, but you could see enough in a full day. You could either (a) spend the day there after arriving, and take a late train to Lucerne; or (b) spend one night in Zurich at the beginning and scrap the night at the end.

We spent two nights in Murren and it was just enough. I would rather stay there three nights than just one. You need to experience both the mornings and the evenings in the Alps.

We spent three nights in Bern, although one of those was a day trip to the Alps, so really two full days. You should see enough of Bern with just one night if you get in early enough one day and leave late enough the other.

You have 9 nights, 10 days? If it were me, I would do it:
Day 1: Land Zurich 8 am, spend day in Zurich, late train to Luzern. Stay Luzern.
Day 2: Luzern and area. Stay Luzern.
Day 3: Early train to Murren. Stay Murren.
Day 4: All day in Berner Oberland. Stay Murren.
Day 5: Train to Montreux. Stay Montreux.
Day 6 and 7: Montreux, Lausanne and/or Geneva. Stay Montreux.
Day 8: Late train to Bern. Stay Bern.
Day 9: All day in Bern. Stay Bern.
Day 10: Train to Zurich Airport.

Thank you... this helps. What would I do with my luggage while we explored Zürich? What about this plan?

Day 1- arrive in Zurich, train to Stay in Lucerne
Day 2 - Lucerne
Day 3 - Murren (Interlaken, Gimmelwald, Bond Train, Wengen, paragliding, etc...)
Day 4 Murren
Day 5 Murren
Day 6 montreux
Day 7 Montreux ( i would like to see Guyere, Vevey, Geneva, wineries, castle, etc)
Day 8- Bern
Day 9 -Zurich
Day 10- Zurich (with possible Day Trip to Rhine or Appenzel)

Thank you so much, i find this very helpful.

New plan looks good. There are plenty of lockers at the Z airport train station for stashing your luggage.

That looks great!
