The trip planner gives a recommendation for specific railpasses for your itinerary. Is there a reason you think it’s wrong?

Your questions are confusing to me…

I have no idea what

means. You ask about convenience but you seem to be concerned about cost. A railpass is more convenient than buying a point to point ticket if you choose to take a train that doesn’t require a reservation. You just hop on the train, no need to stop (and sometimes wait in line) to buy a ticket. I’m also confused by . A railpass will serve as your ticket for any train in the countries it covers. The rare exceptions won’t be an issue with your itinerary. Some trains require reservations which aren’t covered by the railpass. If you choose to take a train that requires a reservation then you have to buy it separately. Most trains don’t require reservations, but express trains (which are often the ones you want to take because they’re faster and they operate at the “best” times) between major cities usually do, so you’ll probably end up taking at least some trains that require reservations. You always pay extra for the reservation. A ticket for a train that requires a reservation costs extra because it includes the reservation. Reservations usually cost about 5 euros but they cost up to about 15 euros for the fanciest “name” trains in Spain and Italy. If you’re referring to add ons to the cost of the railpass itself, you usually have to pay a shipping charge to have the pass shipped to you.

I would look for a cheap flight from Barcelona to Amsterdam. I would either take the overnight train or fly from Paris to Venice. I’d take the train within Spain and for all the rest of this. A railpass will probably save money over point to point tickets in France and Benelux. In Spain and Italy the savings won’t be as great. You can price the tickets on the individual national rail company websites. The links are in a sticky at the top of this forum and under “transportation” on the “travel tips” tab.

Thanks for the long post! You tell me everything that i need.

I was concerned in the cost of the reserve, and if it’s cheaper buy a railpass than a point to point tickets.

You say I will probably save money in France and Benelux, should i buy the eurail 3countries?

You could buy a France/Benelux pass or a 3 or 4 country pass. I’ve not traveled by train Spain, so I have no experience there. In Italy it’s often easier not to use a rail pass because it’s fast and easy to buy tickets (with reservation if needed) from the automated kiosks, but you often have to wait in line to buy “just a reservation” to use with your rail pass. Many Italian trains require reservations. You could price the tickets for itialy at trenitalia.com and for Spain at renfe.com and compare to the cost of a day of the rail pass.
