My husband and I are planning a trip to Europe between mid-August and mid-September 2013 and wonder what we should take into consideration when choosing our dates. Should we avoid August because Europeans tend to take vacation then causing higher prices and larger crowds? Or does that not matter? Are there any national holidays we need to plan for? Are places closed on Sundays or any other particular day of the week? We will be taking delivery of a BMW in Munich and then driving around Europe for about 2 weeks. We are thinking we will go to Zurich, Belgium, Netherlands and Germany with possible additions of Prague and Vienna.
