I swear by rope drop. But, for full disclosure, we are naturally a family of early risers. When at WDW, we rarely set an alarm and are still usually up around 6:00. Not too hard to make it for rope drop when you are up 3 hours early. I do like being at the parks when they open because of the shorter lines. For example, it is not uncommon for us to rope drop Magic Kingdom, see the welcome show, and then head to Frontierland where we ride Splash, Thunder, Splash, and Thunder again before heading to Adventureland for Pirates and Jungle Cruise. From there we go to Haunted Mansion and often also It's a Small World before lunch around 11:30 at Columbia Harbor House. With Fast Passes for Space Mountain and 7 Dwarfs Mine Train, and never any real wait for Carousel of Progress, Peoplemover, Tiki Room, Treehouse, Philharmagic, or Monsters Inc. Laugh Floor, we are able to get everything done that we are interested in with minimal waits for things like Little Mermaid, Barnstormer, and the teacups.
