@Iragersh Thank you 😊! Barcelona: It would likely have been trains for people from mainland Spain and nearby parts of France (and bus for Andorra), but I suspect most other people came by plane. (International train travel is often not as straightforward and cheap as flying in Europe.) Anyway, it is good to let people know about the alternatives.
Ah yes, I see what is happening to the tourism industry in the US.
