Welcome to the DIS!
Make this another vote for 2 days at MK.
You can do Fantasyland, Toontown & Tomorrowland one day (leisurely with a mid day break for rest or swimming) & then Adventureland, Liberty Square & Frontierland the next day. Definately see the parade, fireworks & show at Cindy's Castle. Try to fit in a character meal to add to the fun. LTT is nice. Your dd may be a bit too old for CP. It's probably too late to get CRT but you can always ask when you go. People may cancel 24 hrs in advance so they are not charged on their credit card.
Have an awesome time!
