We had the Ultimate tickets [which include DQ admission] on our last trip but had not included DQ in our planning.
So..., we'd spent a lazy morning in DTD and were thinking of heading back to the car and came across DQ. "Oh, yeah...I've read about this..it's included in our tickets, we might as well go in."
I have to say it is exactly what we suspected it would be...a glorified amusement arcade. Tacky and a bit dirty to be honest. Kids were 9, 12, 14 and not one of them were impressed. Sure, we spent 2 hours there doing Jungle Cruise [cheap idea which didn't really work], Alien Encounter [just rubbish], AstroBlasters [dodgems with frustrating "cannons"], Ride the Comix [these 3-D headsets didn't work 20 years ago, but Disney is still using them], Pinball Slam [????].
Without a doubt, it was the poorest Disney experience we encountered.
Do it only if:
1. You don't pay extra at the door.
2. You have nothing better to do.
