We are flying into Zurich, then going Lucerne for 2 nights, followed by Interlaken for 3 nights, and Montreux for 2 nights.
We have 6 more nights after Montreux and are looking for ideas on how to fill them.
We are planning to spend at least 2 nights in Bern and probably spend our final day in Zurich.
Is it worth adding Geneva with a day trip to Annecy?
Thank you.
