I’m spending 2 months in Europe—1 week traveling, 4 weeks in Florence but planning to go on weekend trips then 3 weeks travel. I want to get a Eurail pass but I’m not sure which makes the most sense. Do I just get a straight-up 2 month pass? Or only get the pass for the 3 weeks at the end? The week of travel will be from Prague to Florence with Munich and Vienna in between probably; while I’m in Florence I want to go all over Italy and possibly to Spain. The 3 weeks are unknown. Does anyone have any advice/ideas?
