My husband and I will be traveling to Switzerland in May for 9 full days. We will arrive early in the day in Geneva. Our plan is to leave Geneva immediately and head to Lausanne which will be our base. We will tour together for 3 days until he has to attend a conference. I will be on my own for 5 days and then we will have 1 day to go back and tour Geneva. Do we buy an 8 day Swiss Saver Pass and then pay full price on the final day in Geneva? Or do we buy a Flexi Pass and I pay half price traveling alone? Thanks in advance for any input.
