Hi, Cheryl!
Thanks for the kind words; it's our pleasure to help make magical experiences for Disney Guests!
Your children are a bit older, and I am basing on my recommendations on the idea that they will not need naps or midday downtime.
With your Saturday - Saturday schedule, I'd suggest heading over to a water Park on your arrival day (contingent, of course, on what time you get in). I'd likely not have you all go to a Park; travel can take a lot out of a family, and some fun splashing time might be just the ticket to refresh your group.
Think about alternating the Parks with water Parks. I'd put Magic Kingdom as your midweek highlight, as the crowds do tend to peak on the weekends at that very popular destination.
How about spending Sunday at Animal Kingdom? That's not going to eat more than a full day, and depending upon your energy level, you can take off for more water or head over to a Park for nighttime fun.
Monday, head to Epcot. That will be a full day.
Tuesday, hit another water Park.
Wednesday is Magic Kingdom Day!
Thursday, you can spend in the water again, or give DisneyQuest a try. When you've exhausted that area, return to a Park for the nighttime events.
Friday is Disney's Hollywood Studios. That's a smaller Park and can certainly be managed in a day. Consider booking a
Fantasmic! meal package so you are guaranteed a spot at the don't-miss Fantasmic! show.
If I can help with more specifics or tweaks, feel free to drop a line.
Have a great trip!
See you later, celebrator,
