I've got a trip coming up (leave Saturday) that starts in Zurich for work and ends in Paris for pleasure. It's my first real vacation in almost 10 years. (Visiting my family doesn't count as vacation, even if it's near a beach.) Anyone have any must-see recommendations for either city? I really only have one day free in Zurich but I have 3 days in Paris. I went to Paris in high school but it was kind of a blur. Any recommendations would be appreciated!
