I am used to travelling by rail in Europe, and have just booked a trip to Barcelona, travelling by Eurostar to Lille, and then to Nimes for two nights, then on to Barcelona. I’m having a long weekend in Barcelona with my daughter and her husband and the two grandchildren. I will travel back via Paris. I can’t comment on package or organised trips, but my tips for independent rail travel are: 1. Use the website seat61.com to research the best routes and for lots of information about transfers, hotels and lots of other things. 2. Travel light: I use a cabin bag and a tote bag even for two week trips 3. booking.com is consistently good, but I always check prices with the hotels’ own websites. 3. Book the cheapest room you’d be happy with at your hotel, then enquire about an upgrade when you get there. 4. RailEurope and thetrainline are the easiest sites to use. 5.first class is often only a little more than standard class. 6. Book a solo seat on TGVs, upstairs for the best views. 7. Buy a picnic at the station before you board rather than buy food on the train. 8. Book a cabin rather than a reclining seat on ferries and sleeper trains for greater comfort and security.
