The crowds should be fairly light until about the 11th or 12th. The you get President's Day Weekend as well as Speed Week in Daytona and the parks can get very crowded.
Also, because of SpectroMagic the benches will start to fill up early. The nights Spectro is on you will have to be in place before 5:00 to get a seat, for the nights without Spectro you will still need to be there by 6:00 to get seats.
As fat as theater shows you will have a problem. Generally to be able to get a seat at the end of a row, near the exit, you have to be at the very front of the line to enter the theater. And the lines can be crowded as often the waiting arrea will hold far fewer people than the theater and the CMs will tell people to fill in all available space in the waiting area.
