TRON Lightcycle / Run at the Magic Kingdom has experienced some significant down time today. The attraction did not progress any boarding groups between 12:11 PM until 4:45 PM! As of this writing, it is only at group 77. It averages 178 boarding groups a day all time.
The roller coaster could be heading for its lowest boarding group total ever during normal operating hours (it did a soft open with limited hours earlier in the year).
