My three experiences on different trips with GOTG have all been ILL$ because I don’t wake up at the crack of 7 to play the Virtual Queue game, but they have all generally been:
1. Walk into the room immediately before the first preshow;
2. Wait length of first preshow for it and then go in;
3. Length of 1st preshow;
4. Length of 2nd preshow;
5. About 5 minutes or so of line after the 2nd preshow till boarding. Yes there’s a line after the second preshow but it moves quickly because it empties into both sides of the track. It’s like standing in the last leg of the BTMRR line if the BTMRR line didn’t make you pick a side and instead emptied to both sides. It moves quickly.
Edit: To be fair, after the first time I knew where the exit doors for the 2nd preshow were so I tended to stand closer to them. I suppose if I was at the very end of the line that formed after the 2nd preshow my wait might have been closer to 10 minutes than 5.
