Planning on a Disney Trip with my 2 and 4.5 year old... we didn't buy park hopper tickets and were planning on doing one park a day, but looking at the rides/attractions, it doesn't look like there is much for my toddler/preschooler at California adventure, so maybe we should just do two days at Disneyland? I just don't want to "waste" a day at California adventure if there's not much for them there.
