I read somewhere that on dueling dragons, you don't have to go all the way back around to the front. There was some kind of door or entrance that you could go through to get back in line without doing that. Does anyone have any info on this?
They have signs that point to the "re-entry hall". That hall is available for use very frequently. If you dont see the sign, it's because they have a long wait. Otherwise, ride as much as you like.
If the re-entry door is closed you can also go up the flight of stairs that have been installed at the exit to avoid walking all the way out to the entrance again.
If you're going to use the re-entry doors, look both ways before entering. There are people coming down the hallway that don't know about the door and it's kind of dark inside. I've scared a few guests by popping out the door!
