Although Disney is much more famous, and a lot of fun for children, their primary goal is profits.  Yes they do donate to causes, but certainly no where near their total profits each year.  Sea World and Busch Gardens, both owned by Busch Breweries, is more concerned with conservation.  You learn more going to their parks, and save a bundle while you are at it, than you could ever learn from Disney.  Busch parks enlighten the mind while they entertain you.  Every vacation should include at least a day or two at each of these parks.
