Packy,
You didn't say if you were staying in an on sight hotel. If you are, then you don't have to worry about lines(except for front row of coasters). If you like coasters you MUST ride in the FRONT ROW of Fire and Ice (Dueling Dragons). It's just not the same in the other rows. Hulk is my favorite coaster. Spiderman is awesome. Seuss Landing is eye candy. We noticed something new every time we walked through. Jurassic Park River ride is good. We didn't want to get really wet, so we skipped ripsaw falls and Blutos barge.
At US we love the Terminator and MIB and ET.
