My husband and I are traveling to europe this september for 19 days. We are traveling alone and backpacking. We want to sort of leave our itinerary open but, need somewhat of an idea of where we are going. We want to see all of europe in multiple trips. So basically we need ideas on the most logical way to split up europe into multiple trips. We would like to see london, amsterdam, paris, and munich(for oktoberfest)for this trip so far. But that is open for suggestions as well.
