I think I've said this to you before. You really need to read the Unofficial Guide to WDW. You ask so many questions every day about touring the parks, and almost every question you ask could be answered with that book.
The book also says that the "go to the left" strategy is bogus.
After experimenting with a variety of ways to tour MK, I think I perfected my strategy on this last visit. Choose an extra magic hour morning, arrive at the park around 7:45 a.m. (a few minutes before opening), which means leaving your hotel around 7:15. When they drop the rope go straight to Dumbo, then Peter Pan, then Pooh, then Tomorrowland Indy Speedway, then finish up the rest of Fantasyland except Mickey's Philhmarmagic, then go straight to Toontown and see anything you want to see there as soon as they drop the rope (at 10 a.m. I believe), then go back and see Mickey's Philharmagic. If you follow my strategy you'll have completely finished the most congested section of the park by 11 a.m. without waiting in a single line.
