There used to be a DisneyQuest here in Chicago. We were so excited to have something "Disney" like that so close to home. We went. We found it to be dark, claustrophobic, loud, and expensive. It went out of business very quickly. I'm surprised the one at DTD is still open. Disney rarely makes mistakes, but DQ was one of them. I guess it stays open at DTD because it is Disney World.
We're going on our 6th trip to WDW in 7 years this coming July. There is so much more to do at WDW, that we still wouldn't even think of spending time or money at DQ. We go to DTD every year and love it...but we walk right past DQ with no interest.
