I'm going the 6th thru the 8th, staying at the RPR.
Actually, there is an attack plan, even if you have FOTL.
The park will open at 08:45am, they won't officially announce this, but they just open early. Be at the gate early for whatever park you visit.
My attack plan web site is here.

Look at the Thrill Ride tour of IOA, and then the regular tour of USF.
The main thing is, you want to go into the park early so you can get a front seat ride on Hulk, front seat rides on Deuling Dragons, and then try for a ride on Pteranodon Flyers before the kid rule goes into effect. FOTL will get you on Hulk and Deuling Dragons with no wait, but if you want the front, you have to wait for it. If the front doesn't open, I just ride in row 2 and enjoy the ride.
At USF, it's fun to walk thru an empty Mummy queue and take it all in.
Now, I do have a little trick since you are going alone. For the coasters, wait in row 2, and watch the people ahead of you in row 1. If there is an empty seat, say excuse me, move thru the crowd, and take the empty front seat. This works all the time for me and I end up in the front with no wait.
Go back to your hotel in the afternoon for a nap, change cloths, have a few drinks, and come back to the parks when the sun is going down. They'll stay open until 10pm and then have fireworks. Go to IOA and watch the fireworks, a good spot is behind Mythos.
