Our flight is scheduled to arrive in Madrid at 6:05 am on Tuesday September 13 and we plan to go directly to Seville. There is a train at 11:50 and another at 2:00 pm. Assuming my flight is somewhat on time is it reasonable to buy the 11:50 am train tickets? There is also an option for "semi flexible" for an additional $8.00 but I wasn't able to find a definition of what that meant. Also, is it better to take a train or bus from Seville to Granada? All comments appreciated.
