i’m puzzled where to go. Central Europe or Los Angeles?

Hi! I’m really balancing whether I should have a vacation in Los Angeles or in Central Europe. If I’d go to Los Angeles, I could have a 12 day vacation + a Baja-Mexican Cruise. But if I would go to Central Europe (Munich, Nuremberg, Prague, Vienna, Budapest and Salzburg), but it had always been my passion to go to castles, but my children wants to go to Disneyland and Universal Studios and Hollywood. I’d like to ask your opinions…
