Did you get park hopper tickets? If you are planning on going over to California Adventure and wanting to ride the Radiator Springs Racers then I do have a suggestion for you. Make sure you ask to sit in the front. We took my 7 year old in July and we sat in the back not knowing that kids can't see really anything in the back. Which really wasn't fair since we waited 1.5 hours to get on the ride. One of the workers heard me talking to my son afterwards about not being able to see and they gave us a fastpass ticket. Awesome! We jumped right back in line, waited 10 minutes at the most and sat in the front. He saw everything and enjoyed the ride so much better than the first one.
We used Ridemax which was very helpful. They offer tips on where to stand for the parades, fireworks, and the water shows. It plans out your day, you tell it what time you want to be at the park and what rides you want to ride that day and it works out your schedule for the day. It was great! We got to ride all the rides we wanted to with very short wait times (except for the new Carsland which had just opened, we waited awhile for those rides). We went first thing in the morning and stayed until around 1pm. We went back to the rental house and took a nap, ate dinner and then headed back there around 5-6pm and stayed until around 11pm-12am. We are already planning for our next trip next summer and we will be purchasing Ridemax again, best $15 I spent. Here is the website in case you want to review it.
