I never try to navigate the Renfe site anymore, but book through Loco2 or Trainline. Either is SO much easier.
That's a moot point now that you've got those bus tickets,
@HalfDomeOrBust , but for future reference.
May your hospi time be rich and wonderful!
I get renfe tickets consistently from USA with no problem. It is likely that it is your credit card company that is stopping the purchase. Loco2 and trainline.eu are two good options. petrabax.com is a company in USA that adds a small fee but also books renfe tickets and you can also print at home.
If you are having trouble with your purchase through renfe and need assistance read this section below from website of man in seat 61 (seat61.com)
Pretty much the
only reason to battle with renfe.com rather than buying easily from
www.loco2.com or
www.trainline.eu is that it may allow you to select a specific seats from a seating plan, although only if buying an expensive
Flexible fare, and only if you manage to spot the easily-missed link. However,
www.loco2.com or
www.trainline.eu allow you to choose seating options and they both show you your seat numbers before you pay, so you can always
compare them with a a seating plan then run multiple enquiries if you don't like the first ones you are given, adding seats to your basket until you get ones you like. Then cancel the ones you don't need and pay for those you do.
If you want to try using Renfe.com
please read the advice on using Renfe.com below. It frustrates many people, though I have to say it has always worked fine with my own credit card and it now also accepts PayPal.
Renfe.com also doesn't handle connections well, so if you want to book (say) from Bilbao to Seville you'll have to guess that this involves a change in Madrid, then book as two journeys, Bilbao to Madrid and Madrid to Seville - whereas Loco2 can generally book from anywhere to anywhere as one transaction, even if connections are involved. The advantage of using renfe.com is that (a) it sells in euros which you may prefer if your own bank account is in euros, and (b) it allows you to pick a specific seat from a numbered seat plan graphic with all fares Promo+ and above (i.e. not if you buy the very cheapest Promo fares). Loco2 allocates your seat, but allows you to see the proposed seat number before you pay, so you can always re-book if you don't like it. For more info see: How to use Renfe.com @ man in seat 61.
