Okay. I have two bits of information for you. The best, fastest, and not too expensive way of getting from Madrid to Seville is by the AVE (pronounced avay) train. It takes a little over two hours and is very sleek, fast, and modern. Second, there is an amusement park In Seville. I don't remember what the name is but it is on the opposite side of the river from the bullring. Also, the best way to get around Seville is the Taxis. They are cheap, easy to spot, and very affordable: only about 1 dollar a mile, maybe cheaper. Try not to rent a car, driving there is crazy, and parking is hard to find and expensive. Have, a great time. My wife and I loved Seville. Don't forget to see the Reales Alcazar.
