We were thinking of spending one full day at Disneyland Park and one full day at California Adventure park. DD1 is 4 and DD2 is 1.5. We're thinking of just doing the 2 day, 1 park per day pass but now I'm wondering if it's worth it to spend more and get the 2-day hopper pass so we can go back and forth? For those that got the park hopper, was it worth it? And if you didn't get the hopper, did you wish you did?
