I never intentionally set out to nap, but despite my best intentions, I have never seen the entire Hall of Presidents show, I have never lasted beyond the dinosaur room on Universe of Energy (which is ridiculous that I can't make it that far), I usually doze off at some point on Spaceship Earth, occasionally on Living with Land. I have dozed off during the Lion King, the Seas ride, the Little Mermaid ride -- all unplanned. I usually am grateful to fall asleep during the Tiki birds show. Basically, if it is dark and slow moving or stationary, I've fallen asleep. However, this happens to me outside the parks too, so it's not surprising to me.
