Well there ya go, things will work out perfectly. The parks stay open until 10pm in July. It's one reason I booked my trip at this time. Go early, get front seat rides on Hulk and Dueling Dragons, go on everything else using your magic key. If you wish to eat lunch at the Hard Rock Cafe, go there at 11:30am to beat the crowd. Everyone gets hungry at noon, the lines are long, and service is slow. People who show up to the HRC at 1pm complain about their experience. People who show up at 11:30am have a great time.
From 1pm to 4pm, relax at the hotel and stay out of the heat. Let the dummies who show up at 11am get a few rides. At 4pm, have a few drinks in your hotel room as you get ready to go back to the parks. A styrophome cooler stocked with beers is a good idea here, you take care of that before checking in.
Now it's 5pm and you're back at the park. Everyone is leaving because they are tired, and worn out. Grab a happy hour drink, the party is just starting. Use your magic keys and ride, ride, ride, the express lines will be short.
At 10pm, you get to watch the fireworks, then walk back to your room.
