It wasn't clear from your original post, but I hope you have a few "rest days" scheduled into your trip? With kids of that age, going full tilt with 6 park days in a row is A LOT. If you are only actually at Disney for 6 or 7 days, I would do a "rest day" at the pool or a water park, etc., instead of planning another park day. 5 days in the parks should be plenty at that age...
