I agree with PP's, it is a fantastic, slow, cool dark ride through the history of communication with some cool effects. It is a great ride to go on in the late morning, or early afternoon. Typically the line is pretty long first thing in the morning when everyone comes into the park. I use that time to hit up the E ticket, and then other attractions on one side of Future World, then head for Space Ship Earth toward the end of the morning, before going into the World Showcase.
