This little tip we have found to be so helpful.
Go to the park with Early Entry! Enjoy the hour of rides without long lines. When the park opens to the general public, have breakfast @ the park, then leave that park for one of the other 4 parks. Be sure to have PS's for the breakfast.
Since you will be up early to do the EE, be sure to do the afternoon nap/swim/rest at the resort. Then spend the evening at the park of your choice (best to choose the non-EE park) and take in the fireworks or parades.
If the park's "regular" opening is 9:00 a.m. Early Entry will be @ 8:00 a.m.
Hope this info helps!! Have a great trip!!!
