I usually recomend doing EE early in your trip. As the days go on you'll find yourself getting very tired and its hard to get the family moving in the morning. Especially after a night of late fireworks or F!. I would plan for Monday, then play the rest of the days by ear and see if you can make it. It is very nice to be at the park early when the lines are short. I've never had regrets over going to ee.
