I am having a hard time coming up with an itinerary as well as decided on rather I should travel by rail by plane or a mix of both. Also, I don't know which order I should visit each country to so I am not back tracking all over Europe.
I would like to visit:
Paris
Amsterdam
Barcelona
Madrid
Rome
Florence
Poland (Auschwitz)
Switzerland (Zurich and Interlaken)
I have 30 days in europe and am traveling on a budget (think hostels, low cost meals...lots of picnics) Also, I am 28 so I don't qualify for a student/discount rail pass.
