This seems to work for us! We do the Magic Kingdom from back to front!
Most people head straight up Main Street or linger for photos and autographs with the characters. Try this approach;
Arrive at opening. When the gates open, catch the train to Frontierland, which lets you off right at POTC, and tada! no one is in line (last year the CM gave us a trading pin and told us it was for being the first rider of the day!

) High tail it over to either BTMR or Splash Mtn or Haunted Mansion and once again, barely any one in line!(mind you we were NOT running or "commando" touring, just walking at our pace). Check out some of the minor attractions, snap some photos and head to Fantasyland. This is usually where you run into the first crowds of the day (mostly families with little ones). Keep going through the Castle into Tomorrowland and fast pass Space Mtn. Now it's around lunch. Eat, relax and take in the scenery! Most of the rides are done and you beat the crowd! Now check out the lines on the rides you missed or do what we do... head back to the resort for a dip in the pool!
