My husband and I are planning a trip of 16 days to Switzerland and Chamonix, France next September. The first 4 nights are in Wengen, then 3 or 4 in Chamonix and then on to Zermatt and/or Riederalp/Bettmeralp area in the Vallais before spending the last 2-3 nights in Lucerne before flying home from Zurich.
My question is should we spend 3 nights in Zermatt and then a couple of nights in one of the little villages of Riederalp/Bettmeralp OR spend 5-6 nights in Riederalp and use it as a home base and visit Zermatt as a day trip? Would that be enough time for Zermatt and the Matterhorn? It's about a two hour trip to Zermatt from Riederalp.
