Well, I can tell you that operations are already in mid season form. Five minute dispatches and 1 train ops.
But seriously. It is what it is, and will always be. I don't have any specific recommendations re. food. The lines get long quickly, and stay long all day, so keep that in mind. Nevertheless, you can do absolutely everything worth doing in 2-3 hours, sometimes less.
Here are some other random tips:
1. Voodoo Drop packs a punch. It's worth it.
2. I'm a big fan of Rodeo.
3. When you ride Wild One, don't sit on a wheel seat, it will greatly improve your experience.
4. Do the 10-15 minute walk to the back of the park where Batwing is first, and then work your way back.
