hello moderator,
i must start off by thanking u for all the feedback this site offers promptly.
i will b in interlaken for a week n i intend doing jungfrau, schilthorn, tummelbach falls, mt titlis, montreaux, berne, zermatt,harderkulm,ebike tour of interlaken, n then proceed to zurich where we will stay for 4 days when we visit the rhine falls, lucern, lugano , n do a tour choclate n cheese in zurich......since both me n my hubby are 50+, i feel at times if this seems very ambitious, do i need to make changes, if so what can i skip .....
i will b taking a 15 day second class swiss saver pass, can i upgrade some journeys like montreaux, lugano to first class n how do i do that, can i do reservation of seat after i reach interlaken , n how do i do that,as i m finding it difficult to do the reservation online....
what will the weather b like in june 6th to 17th......i must have enquired earlier but i cant trace the answer....
will b highly obliged,.......thanking u in anticipation
Ash.

is it more convenient to go to mt titlis from zurich, since it takes 1 hr more from interlaken.......please suggest

i have been to first barn, grindelwald,ballenberg museum, on cruise across brienz...

Hi,

In that case you could consider to skip the day trip to Zermatt. It is beautiful there, but traveling to Zermatt from Interlaken is a long trip and you'd leave one magificent mountainous region to see another. Montreux and Lugano are in the south of Switzerland and have a different atmosphere than the other places on your list such as Zurich and Interlaken, so it makes less sense to skip those if you want some variety.

I would recommend not to make such fixed plans. Just take along a list of possible day trips and make further decisions while in Switzerland. You can just do what you feel like and what the weather allows. That's the advantage of having a Swiss Pass: you're flexible. If the weather is great for the Titlis, you can visit it from either Zurich or Interlaken. The forum and the rest of this website offer many ideas, here and here for example.
