Need to get to Madrid from Sevilla and daughter wants to take train.
The AVE (bullet train) will cost somewhere in the neighborhood of €15-€25 more than a regular train, but will save you about 2 hours. Really, it all depends on your economy and how long you have for your trip. www.renfe.es is the official site for Spanish trains.
the ava is the way to go. Quick and very pleasant.
