Ride Strategies To Avoid the Long Lines

KIDS
Dumbo, the Flying Elephant: This ride will always have a long line throughout the day, so strategy-wise, go to this one first, if it's on your list.

Peter Pan - Similar to above, for some reason this very, very short ride always has a long line. Try to plan for it first thing in the morning.

TEENS, YOUNG ADULTS, ADULTS, SENIORS AND SOME KIDS
----------------------------THINK MOUNTAIN!!----------------------------
Depending on which side of the park you decide to try first----

Space Mountain - located in Tomorrowland (to your right after Main Street)

Splash Mountain - located on OPPOSITE SIDE OF PARK in Adventureland. You could get your first fast pass here, then go to the moutain coaster ride nearby (see below)

Big Thunder Mountain Railroad - also located in Adventureland, right nearby Splash Mountain.

You could also go over to Space Mountain, get a Fast Pass. Then, get over to Adventureland to wait on a fairly short morning line and ride Splash Mountain, then head over to Big Thunder Mountain Railroad.
