they only have the disneyland park and the studios, tower of terror opened in january so i had to go and check it out they have just added a few more rides to the studios. Maybe it was busy because of that.Can't really say how big it is you can probably do the main park in a day depending on low crowds and the studios in just over half a day there is not all that much in that park.
How is the little one feeling now i read that he is poorly today
