Nancy,
Well we are probably a bit far out there to plan specific days, but here are some things that I think you should consider. Review what I have here, and ask me follow-up questions on what interests you and we can just plan from there.
Park days: With a 7-year old focus your mornings on getting into a park early. See the sights and stay up to or through lunch.
Afternoon Activities: After park mornings, use the afternoon to relax and try alternative experiences. Since you will be at Fort Wilderness, try as many of their activities as you find interesting, like horseback riding, boating, camp activities, and of course time at the pool.
Evenings: This is where your resort choice really is a plus. Go to the campfires, and get a reservation at
Mickey's Backyard BBQ and the
Hoop Dee Doo Review.
Now that is a starter for your planning. Since I can only fit so much into a single answer, write me back with multiple questions on fun breakfasts, dinner shows, Downtown Disney and other nighttime activities, etc.
Also, let me know about your family's interest, so I can customize a bit more.
Have a magical vacation!
