Thank you for your comments.
First of all, I want to ask you to understand that in any cities there is much more than just tourist attractions. In Geneva, I'd like to visit Reformation Museum, St. Peter's Cathedral, Bastion Park, and Palace of Nations (with Red Cross). I'd like to see the inheritance of John Calvin since I'm Presbyterian.
I don't know if I have enough time to go to Lauterbrunnen for the first night after visiting those places in Geneva and Olympic Park and Museum in Lausanne. What do you think? If it is possible, I'll stay in Lauterbrunnen from the first night instead of the second night.
If a day trip to Lucerne is possible, I'd like to stay in the same hotel in Lauterbrunnen until the fourth night and then move to Sion to St. Leonard and some beautiful places around there and then catch the train to Venice on the next morning.
