We're in the process of planning a 12 day trip at the end of May to Europe. One itinerary we're working on is:
Days 1-4: Prague, with day trips around this area
Days 5-7: Hallstatt, Austria with day trips around this area
Day 8-12: Stop in Lichtenstein on way to Lucerne with a visit to Mt Titlis and then Zurich
We love to hike, being out in nature, walking around towns, trying new wines, and visiting breweries (or pubs) to try new beers. We will be using public transportation (bus and train) to get around Europe. How much time should we plan to spend in Lucerne and Zurich to get the most of our trip? We are willing to be flexible with the amount of time we spend in Austria and Switzerland. Many thanks in advance.
