We will be arriving at El Prat on Vueling airlines from Sevilla at 10:25am on a Tuesday. Trains from Sants to Nimes leave at 1300, 1316 and 1516. Which would be the best time to plan on leaving Sants?
Are you asking how much time you should allow to get from El Prat to Sants, to catch the train to Nimes? The train from the airport to Sants takes about 20 minutes; and Renfe suggests arriving at your platform's waiting area about 30 minutes before departure, so you should be able to make the 1300 train easily if your flight lands on time.
Thanks. Timewise I thought the 100 would be fine but having never been at the airport or train station wasn't sure how confusing they might be.
