Trip to switzerland from November 25 to Dec. 1

Hello yashvananda, and welcome to the forum! Lucerne and Interlaken are both great resorts for exploring some of Switzerlands most beautiful regions, to that's a good choice. Lucerne-Meiringen-Interlaken is part of the Golden Pass line, so you can easily travel this route.

If you want to visit St. Mortin in the western part of the country too, the Glacier Express and the Bernina Express don't fit in your itinerary that well. If the Bernina Express is very important to you, you could choose to travel to St. Moritz in the south-east and then make the Bernina Express trip to Tirano, but that would be a long detour, requiring you to spend one or two nights in or near St. Moritz. The timetable will help you decide, as it indicates connections and traveling times.

If you want to be flexible and adapt your plans to the weather, a Swiss rail pass would be very convenient (and in definitely more economical than buying regular point to point tickets). The 8 day Swiss Saver Pass may be a good option for you, as it allows you to travel anywhere throughout the country on all days of your stay. It'll make it easier to travel to a region where weather is fine, and train rides are very enjoyable, even if it's rainy. Furthermore, you could look into boat trips over the lakes near Lucerne and Interlaken, museums (such as the Swiss Transport Museum in Lucerne), and so on.

Does this get you started?
