Parque des Attraciones is a lot of fun, and teenagers will like it. It made me feel like a teenager myself. There are lots of rides, some of them scary/fast -- others slower, also bumper cars, merry go round, ferris wheel, etc. It is kind of like a large traveling carnival without the shadiness. Festive but also safe. Some of the lines are long, but there are plenty of other rides if you can't face a particular line. I spent a whole day there with friends when we wanted to get away from museums and cross cultural observations and just hang out and have fun; it was great. Don't wear nice clothes if you are going on the water-rides; you get soaked.
