Can one take the train or public transportation on a Sunday morning between Sitges and El Prat airport to catch a 10:45 am flight to the US? Thanks!
My info is from 2006, but since no one else has chimed in... There are fewer trains on Sundays, but it looks like a couple an hour starting around 6:00 a.m. It's six stops and takes about 30 minutes. On renfe.es, you would look for Cercanias line #2: St. Vincenc de Calders/Vilanova - Macanet.
Thanks for the information, Janet. Very helpful!
