Yes a lot of the stops are due to them having to stop the cars to assist a special needs person who is not mobile on and off the ride. Haunted Mansion and Buzz Lightyear have the same type loading system and have to stop also if someone cannot enter on the moving walkway system. Spaceship Earth appeals to most guests and I think more non mobile people ride it than any other ride, we always seem to stop. DH and I do enjoy it, though it is dated now we ride it at least once each trip and often two or three times....
