It's been said many times on these boards that there's no wrong way to tour WDW.....but this is a prime example of the wrong way to do it. When you're burned out, when you're exhausted, when it's not fun anymore.....you're doing it wrong.
OP, using the touring plan app is not gonna fix what's going wrong with your vacation. It's likely going to make things worse, and make your family even unhappier. You're trying to do too much. Way, way, too much.
The beauty of WDW is the huge variety of fun things to do that are NOT in a theme park. Your resort pool. Fun activities at the resorts, like movies on the beach. Recreational activities like boat rentals. Shopping and dining at DTD. La Nouba. Disney Quest. The water parks. Golf. Checking out the other resorts. Nearly anything that suits your fancy.
Stop. Shut down the touring plans app. Do something different. Go to the parks for awhile in the morning, then come back and swim at the resort. Relax. Go back to the parks after dinner, when it's cooler and less crowded. Tomorrow, go over to DTD in the morning , then hit a water park in the afternoon.
Staying in a theme park for 12 hours may be some people's idea of a fun time, but it sure isn't mine. Go by what's right for your family, not what the books and touring plans say.
And take this advice from a veteran WDW visitor - more than 30 trips over the past 25 years. The surest way to guarantee that you'll have a lousy WDW vacation is to do too much because you're afraid you'll miss something. Is this a vacation, or checking boxes on a to-do list? It's supposed to be fun. Go have fun.
