The 30-Day Europe Travel Planner.

Thirty days is enough to see ten of Europe's great cities without sprinting: this planner gives you one tested route, Amsterdam to Lisbon, with 29 nights, mostly by train, and every booking you need to make before you leave. The route is open-jaw: you fly into Amsterdam and home from Lisbon, so you never backtrack. It moves through the Netherlands, Belgium, France, Switzerland, Italy, Spain and Portugal, with two or more nights in every stop and four nights in Paris and Rome, where there is most to see.
