We plan to spend a few days in Santiago after the RS Barcelona-Madrid tour in June. We'd prefer to take a train from Madrid to Santiago (and back), but it looks like the train trip can take from 5 to 12 hours or more, and we can't seem to find reliable information/schedules. Flights are quick and cheap, but we'd like to see the countryside. If a train trip is 6 hours or less, we'd prefer that.
Any tips on sorting this out?
