You've spent a good chunk of your life savings on this trip, and you're going to make the most of it. You make a minute-by-minute schedule of when you need to arrive at the parks, which rides you'll visit in what order, taking into account usual wait times and your FastPass+ reservations, how long you can spend eating meals, and where you should stand for the fireworks show. This trip is going to be as magical as possible, even if it kills you.
