Parks will be crowded if ep prices are that high
Plan on arriving at the parks early before they open to the general public if you are not staying at one of the 3 deluxe onsite hotels
Use the single rider lines where they are available
Eat at off times in the park to avoid long waits
Have a plan in advance
Check out
