I know it's not completely impossible, but how do you go about doing Disneyland/California Adventure in a single day? It looks like that's about the only way I'll get to go, and I have to wait until the middle/end of January. What rides are must-do's? How exactly do you cram everything into one day? Obviously, we plan to skip the little rides that we are much too big for now... I think what I'm most curious about is how to best navigate the park in order to accommodate everything.
