Hi, Regina! Two days is not a lot of time to cover such a wonderfully huge place, but it's certainly better than nothing! With a 10-year-old girl, I would suggest just focusing on the Magic Kingdom and Disney's Hollywood Studios. Take a look at the calendars for the
Magic Kingdom and for
Disney's Hollywood Studios paying particular attention to the parks' hours, Extra Magic Hours (if you're staying at a Disney resort), special events and entertainment/parade schedules. Then, map out your days' schedules according to what interests you most. The more you plan, the more you'll see and do, and you'll get the most of your WDW vacation. If you have any "wiggle room" perhaps the night before or the day after your park days, you may want to consider making
Advanced Dining Reservations at one of the many restaurants outside of the theme parks including Character Dining. You'll get a Disney experience without a ticket! Otherwise, I would stick to fast, counter-service meals and snacks for the days you are in the parks. I hope this helps in the planning process. Let me know if you have more questions. Have a wonderful day and a magical vacation!
