I am Planning to spend two days with family in Zermatt and Interlaken two days , which one will be preferred staying in Zermatt two days or Lucerne two days . My starting point is Montreux , I can travel to Interlaken , stay for two days and travel to Lucerne stay for two days . From Lucerne to Venice . Looks like both Rothorn and Matternhorn Galcier paradise both not open during the period ( April 28 to April 30 ) .
Thanks in Advance
