That dd/dc que sounds confusing. Ive never seen it before but how do you get lost in it? Are there like a bunch of random tunnels?
I wouldn't call it confusing just there is one section where you can re-ride this means once you have rode the ride there is a passage joining on to the original queue saving you having to queue up in the entire queue again, now if there is a very small queue when you go through the re ride tunnel and join back on to the queue it can get confusing which way too go i believe there is a very small sign reading 'to the dragons' but can be easily missed and now with the refurb things are just a whole lot worse.
