They opened at 6am this past Sunday. It was a zoo. We were there. They initially told everyone that Boarding Groups for Rise of The Resistance would open at the normal park opening time. At 7:40ishAM, they made a parkwide announcement that they were open. Only EMH attendees were in the park at that time. We just happened to be coming of Midway Mania. If we had still been inside the ride, we probably wouldn't have gotten one. They were all gone by 8. There were a LOT of ticked off people at park opening.
