I don't want to spoil your holidays but underneath you will find some pictures and information about the Dragon Khan and Templo del Fuego, the 2 best rides in Port Aventura. If you had the choice I should visit that park. In combination with Barcelona (most beautiful city of europe in my opinion).

I have also visited Parque Warner Bros. I liked it, it is a nice park with an awesome collection of rollercoasters. My favorite is Batman over there, it is very intense and above that quite nicely themed. The whole park is well themed and above that it is normally quite over there. So in one day you can do all the rides and your favorite you can even double or triple.
