Hi,
We will arrive at the Frankfurt airport on 8/14/18 and depart 8/21/18. We plan to spend the majority of our time in Switzerland and would like to spend at least 2 nights in Lucerne and 2 nights in Wengen. Any suggestions on where we should spend our first night, either Germany or Switzerland? Also wondering if it's doable to spend a night in Zermatt and/or Geneva. We are also considering renting a car for the drive from Germany to Switzerland and then taking the trains everywhere in Switzerland. Any recommendations are greatly appreciated.
Thanks!
