Sorry Radar, but I have just spent a week at The Grand Californian, shuttling back and forth between California Adventure and Disneyland.
While I always thought that closeness of the hotel and parks was a great thing in Florida, nothing prepared me for being able to walk out the side entrance of the Grand Californian and step directly onto the line for Grizzly River Run in DCA. A few STEPS away was Disneyland. Downtown Disney connects all. The close proximity of both parks and hotels was wonderful.
AND, California Adventure was wonderful as well. There's a lot more to do at DCA than at either the Animal Kingdom or Disney Studios. I love the Animal Kingdom, but DCA has much more to do. It is also a beautiful "Disney" park.
My wife and I have been to all four Disney parks around the world, and California Adventure stands well among them.
AND, it is TRUE that Disney is cryogenically frozen. NOT a rumor.
