It depends on your favorites! If you are interested in new Fantasy Land rides (little mermaid, Seven dwarfs mine rides etc.,), I would start there as early as possible! If you are more interested in Tomorrow Land rides (Space Mountain, Buzz Light Yr)I would start there. I agree with the person above, I don't cross over the park to much, and tend to try to start one place and circle around unless the attraction has a long, long line, (I'll come back) or I'm getting to a fast pass attraction, or eating reservation. Just have a look at the maps and attractions again and learn about the new fast pass, on the Dis boards.com . under Theme Parks. Hope you have fun!
