As the summer months are coming and as trains will be quite busy, we'd like to share with you some tips for reservations with Renfe, Renfe-SNCF en cooperación as well as Eurostar! Here is the link to the Eurail page and here to the Interrail page. As you may know, reservations are mandatory for Eurostar, Renfe-SNCF en cooperación and most Renfe trains.
On these pages you will find some recommendations on how to book your reservations and some tips to avoid them (when possible) on these routes, particularly on the French-Spanish Mediterranean border, as well as in Spain, by taking alternative itineraries.
Experienced Eurail and Interrail travelers, any tips for other travelers on these routes? Any other alternative itinerary suggestion or feedback is appreciated!
