True, but the overhead costs are not being deducted from the $30/person they're making from Caring for Giants, they're being covered by general profits they make from the parks, which kind of makes this conversation more interesting-- it's good that the $30 is going to the conservation fund, but in theory that means guests who will never do this experience are paying for its overhead costs. Although I guess it's not much different than increasing ticket prices and building an attraction some guests don't care to do.
