We have been there twice (at 4 years' interval) and the children loved it both times, even though the first time they couldn't go on too many of the rides. It's got rides for all ages, though, something for everyone. Even for younger children, it has lots of play areas (some with water, so it's best to go during the warmer months). Good choice of food, but it does get quite busy, so I'd advise a late lunch (good chance to go on many of the busier rides, as there are fewer queues at lunchtime).

"Best Park I have been to. Great service, amazing rooms at the hotels (I have tried the Colosseo and El Andaluz). The restaurants inside the park are not bad at all, specially the El Quijote in the Spanish Village (good paella and good sangria!).
The park is split into countries, nice shows for kids and adults."
