Wow people are that worried about their fast pass to get on at midnight. I would be interested to see how many FP+ per hour are available to see if its worth it.
Just thinking the difference between Test Track at 6pm vs 7 or 5 pm really doesn't seem to hit m as affecting anything as I would just plan around it or move dinner or hit up a small attraction at a different time.
People are going to start thinking back to the days when FP was a random time later in the day you didn't know until you pull the ticket.
