I will be backpacking western Europe for 2 months. I'm leaving on monday. The countries I plan on visiting are Ireland (dublin only), UK (london only), Netherlands (Amsterdam only), Germany (Berlin & munich), Czech (prague), Hungary (budapest), Austria (Vienna), Italy (venice, rome), Croatia (dont know), France (Paris and one other city), Spain (Barcelona, pampalona for running of bulls), Greece (athens, going to stay at the pink palace for 4 days) and lastly Portugal (lisbon). May cut out some countries to save time. Going to stay in each city for 3-4 days.
Any tips of where to go, what to avoid, etc would be greatly appreciated. I've already done a lot of research, but I have found first hand tips are the best. Also if you have any recommendations of cities to cut out or add in that'd be great. I have a eurorail pass.
Budget is $140/day
