Are "Preferente" and "Turista" the equivalent of 1st and 2d class tickets on AVE trains in Spain?
If so, is there any significant benefit to "Preferente", or is tourist-class just fine on these AVE trains? (To help you answer, I'll say we travel 2d class on Swiss trains, and 1st class in Italy on the ES trains).
Also, is the Dorado Card (for persons over 60, providing significant discounts) available to Americans, or only to EU or Spanish citizens? Can it only be purchased in Spain?
And now the open-ended question: anything else a newbie to train travel in Spain should know? That is, is there anything significantly different from travel in Italy or Switzerland, with which we are familiar?
And yes, your answer can start, "The trains in Spain are mainly . . ." Thanks.
