Definately getting to the parks by rope drop or taking advantage of the late EMH's will help. I find more people use the early EMH's than the night ones. Usually people don't like to stay late after touring all day. This way you can do it "land" by land.
The reason the plans have you criss crossing is to take advantage of the FP system for the major attractions. These attractions are spread out all over the park.
We usually take it land by land. So we'll go to say fantasyland and grab a FP for Peter pan and while waiting we'll see it's a small world, dumbo, then go back depending on the time you can play it right and get a 2nd FP for say mickey's philharmagic. Then use your FP for PP, ride snow white, then depending on the time you can get another FP for Pooh, Then use your FP for philharmagic, then ride the teacups and play at pooh's playful spot while waiting for FP times to come up for Pooh.
Does that make sense? I think you're still able to get two FP's at a time....it's usually when the time is close to the first FP time.
