I would definitley recommed going for an early entry. The park that has ee will be crowded that day...but there is a good way to go about it. Just go to the ee at the park adn stay there until lunch time or so (whenever it gets crowded) and then head to another park that is not as crowded. You'll be able to do a lot during the ee. It's a nice perk to WDW resort guests so take advantage of it.
