I am trying to figure out best way to purchase AVE tickets to Seville when we (family of 4) arrive at Madrid airport. We arrive 8:30 am and will be heading to Seville directly. Some sites tells me I need to purchase tickets ahead of time to avoid risk of selling out but Renfe site is telling me it will take 7 hours to get to Seville (it's the only ticket option it shows), I think it will be best to purchase once a arrive.
I do know we have to get to Atocha station and transfer to AVE train for Seville. I am trying to avoid buying tickets at Atocha station since from what I can tell from Googling, it might be crowded.
Is there an Renfe office at T4 at Madrid airport? Can I purchase AVE tickets there? Or just kiosks?
Any insight on this will be helpful, thanks in advance!
