I agree with sherilaine, you'll be more productive with the early entry at DL. And after you've covered Tomorrowland and Fantasyland, you can head to Adventureland, Frontierland and Critter Country when the park officially opens and enjoy short waits for Indy, Pirates, Haunted Mansion, Big Thunder and Splash Mountain while the bulk of other guests head to the FP machines in Tomorrowland and attractions in Fantasyland. I love how it takes a while for lines to build on the back half of the park!
DCA is easy to hit all the big attractions with FP and watching the app for low waits. The exception is Toy Story, where FP isn't available and the wait is regularly 35-45 minutes. Try that one first thing, despite early entry, and consider anything under 40 minutes 'as good as it gets'. It's one of the few rides I'll actually wait 40 minutes for if we never get lucky enough to see it lower, it's just so fun, unique and competitive!
Have fun planning!
