Yeah, it's going to be really, really hard to do HC and the MBA in one day. You need about 2 or 3 hours to do HC and about 3 hours to do the MBA. (imho)
When you're in Monterey, try Sea Harvest Restaurant. They have good clam chowder. Or if you're going north, hit Phil's Fish Market (love their chowder, too) in Moss Landing up the 1. I'd avoid the clam chowder in the MBA cafeteria... bleh! But if you do have to eat there, the chicken caesar salads are good. (Ask for Margit, she makes the best salads. If you get the other guy, he puts too much dressing on it...)
I really liked Hearst Castle. There's a book in the bookstore I'd check out. It's called the Golden Days of San Simeon. It talks about all the parties he threw and all the celebs that went for a visit.
