I think there were a lot of problem with Disney Quest advancing beyond the one in Chicago
1. Was choosing to build them in the downtown sections of major cities in the first place, where not only are the costs for rent and taxes higher, but people with families and small kids, who are the target audience, aren't real likely to take their family out of the suburbs, drive to and pay to park in a city. They should have been built in the suburbs, I remember hearing about this thing called Disney Quest coming to Philadelphia and thinking "that sounds like a great concept, by why Philly? 40 minutes outside the city is The King of Prussia Mall, which is the largest shopping complex on the east coast, that's where they should put it". And just recently at The Exton Square Mall, in Exton PA, a Dave and Buster type chain called Round One, which a combination bowling ally/restaurant bar/arcade, opened a location in a huge space that was a former JC Penny store, and the same mall also has a indoor mini golf at a former Abercrombie & Fitch
2. The one flat admission fee always kept me from visiting the Disney Quest in WDW, because if you don't really know what is inside the thing you're not real anxious to pay a fee to find out, plus it seems like it would be difficult to finance all the technology in a Disney Quest with the main revenue being that one flat rate. As a kid in the late 80's and early 90's I dumped plenty of quarters in to Video Arcade Machines, and that pay-per-play system still works for places like Chuck E Cheese, Round One, and Dave & Busters
3. The biggest problem for me was them calling it an "indoor theme park" when clearly it a fancy video arcade. Them trying to over sell it just made me suspicious of ever going to see it... but I love going to The Disney Store at the mall, I just wish there was more to do at the Disney Store than just shop. The concpet of a "Disney Quest" is still appealing though, having a mini, one day, one afternoon, Disney vacation experience close to home is still something I'd go do from time to time. A "theme park" is more than just attractions, it's also shopping and dining, I think if they were to expanded a few Disney Store locations to include dining and Disney Quest type entertainment me and my family would certainly go check it out. We go to the Disney Parks and stores fairly often already
