On long stays (more than 3-4 days) I look at the park schedule to see what parks have the magic hours and avoid those parks for around those times. I also make sure i have an idea about what days i want to arrange a dinner with firework viewings. From there i let the ADR availability dictate where i can eat and when. Then based on where we eat we enjoy whatever show,ride,activities are near after dinner.
I dont put alot of "planning" into what park on what day. I have gotten pretty good about park hopping, so i just know where i need to end up for my reservations.
In everyday life i am very plan driven, but i have found when at Disney things work out better if you are not stressed about sticking to a set plan. With the apps, maps, an schedules that are out there its very easy to go with the flow and make decisions in real time.
