I want to go from Lisbon to Seville by bus.
I know all about alsa.es, but when I try to buy the tickets, I get the information that 'this bus does not have numbered seats'.
What does that mean? How do they know when the bus is full? Where do I sit once I get there?
I'm a bit affraid to wait till I come to Lisbon to buy the ticket, I'm affraid they might be sold out untill then, I'd like to do it in advance.
