This is a fantastic ride for all ages.  It never goes too fast, and features a fun interactive activity at the end.  This ride does go through periods of near total darkness when the area is lit only by “star” lights.  The cars also rotate backwards and go downhill moderately steeply, though not fast enough to cause alarm to children.  It is located inside the iconic giant sphere in East Future World.   The lines are rarely very long and move fairly quickly.   I do not recommend taking children under three years of age on this ride, but you should use the official requirements and your own discretion to make decisions on this topic.  Have fun!
