If MK opens at 8AM, you plan correctly, you can do a ton of the park by 10AM. Since you have FP for 7DMT, don't do Standby. What we normally do is PP, Ariel, Barnstormer, Dumbo, Teacups, Pooh, Racetrack, Buzz, and maybe Astro Orbiter. That leaves HM, BTMRR, Splash, PotC, JC as the remaining big rides. We FP 7DMT, Space Mtn, and something else. The rest of the time are shows, parades, Castle shows, street performers.
