I loved the Parque de Atracciones, but not necessarily for the rollercoasters. They had 2 good ones- El Abismo and El Tornado. Also, there was a giant drop. Besides those 3 things, the rest of the attractions were small things like bumper cars, a virtual reality ride, and water rides. The best part was the show at the end of the evening. It was an amazing percussion group, like Stomp with comedy. If you are around Madrid, it is alot of fun, and I do reccomend it, but if you have limited time, spend some time at the other sites like the Prado or the Catedral. It is extremely relaxing and enjoyable to sit out in the park, listening to the street performers while eating lunch or something similar.
