Here’s more about our successes and difficulties using the Eurail Pass during two months in Europe.

The current price for two adults traveling together, for a virtually unlimited number of trips in 21 countries for two months: $1,409 per person. Other prices, for varying lengths of time, for youths, for a single country or region, in dollars or euros, can be found at Eurail.com.

A few times, there weren’t any seats available for Eurail Pass users. A few other times, we had trouble finding seats once we got aboard. Both of these types of problems were due to the amazing number of vacation days and holidays Europeans get. We found that it was best not to head south as a springtime weekend approaches or north when the work week begins.

To get from Avignon to Barcelona, a relatively short train ride, we ended up booking a train up to Paris, another down to Bordeaux, and another back across southern France, into Spain, and on down to Barcelona. But we’d never been to the town of Bordeaux and it turned out to be such a nice place to stop that we decided to stay on for a couple of days. No problem!

Spain’s spin on the Eurail Pass came as a surprise to us. The Eurail timetable booklet mentioned that some routes required reservations, and that these would cost extra.

It did not mention that nearly every train in Spain required a reservation, and the extra cost was substantial — Madrid to Lisbon, Portugal, $140 extra for the overnight to reserve a sleeping compartment for two, for example. (That’s on top of the initial cost of the Eurail Pass.) Even the short day trip from Madrid to to Granada had a reservation fee of about $11 each.

The round trip between Madrid and Segovia cost $36 each without the pass, but the ticket agent said the fee would be higher with the pass. That was weird.

Although our Eurail Pass was first-class, we saved some money on the train from Madrid to Cordova by going second-class — the reservation fee: $15 each.

Fortunately, the other ten countries we visited using the Eurail Pass had less burdensome rules. Often, reservations weren’t even needed, and there was seldom a problem finding seats in first-class.

Reservations in Germany cost a few extra euros, sometimes nothing at all. In France, from the southern border town of Hendaya, the reservation fee for the train up to Paris only cost an extra $4, and the same for the train from Paris to the lovely coastal town of St. Malo.

From Berlin, Germany, all the way to Copenhagen, Denmark, the extra reservation cost was only $10 each. Finally, we began to think that it had paid off to buy the Eurail Pass before we started our trip. To confirm the wisdom of our purchase, we asked a few prices for traveling without the pass. One example: even for second-class, the cost of a ticket from St. Malo to Paris was $84, and the cost from Paris to Bruges, Belgium, $140. Berlin to Copenhagen, $180 second-class, $285 first-class. And the Eurail Pass is first-class, with all the comforts that provides.

Besides trains from city to city, the pass covers local transportation modes in some places, such as trams and certain metro routes. Check at local stations.

Considering that our farflung itinerary, planned and unplanned, took us to France, Germany, Italy, Spain, Portugal, Belgium, Austria, Denmark, Sweden, Norway and the Czech Republic, we got our money’s worth. We even threw in three days in Krakow, Poland, outside the Eurail Pass bailiwick, with the money we saved.
