Did you know each park at Walt Disney World has a tip board that can tell you the wait times for the popular attractions, parade times and show times? Well, they do! These boards also tell you if attractions are closed, when and where street performers will perform, park hour changes and firework times.
You can find the tip board at the Magic Kingdom on the left side of Main Street as you approach the castle. Look for it as soon as you pass Casey's!
Because of the size of Epcot, you can find three different tip boards all in Future World. The first one is past Spaceship Earth (coming from the park entrance) before you get to the Fountain of Nations. The second one is in the Future World West plaza and the third is in Future World East on the way to MIssion:Space. (If they are going to have three, they could at least share the love with World Showcase!)
At Hollywood Studios, you can find the tip board where Sunset Boulevard and Hollywood Boulevard intersect.
At Animal Kingdom, the tip board is on Discovery Island after you cross the bridge from the Oasis. Look to the right before you get to the Tree of LIfe.
If you can't find any of these tip boards, check your park map (the map should be labeled with a black T) or ask a cast member!
