I still believe that building a TDS instead of a DCA next to DL would have resulted in MUCH higher attendance/revenue
No doubt. But would it have been enough to make up for the additional cost? Given how poorly DCA has performed, I'd say the answer is probably yes, but its a huge gamble. Universal threw money at IoA and struggled. What if the assumptions we make are wrong and Disney built TDS next to DL, only to find it drew no better than DCA? I'm not saying it would have happened, but it would have to be a concern.
Scoop/Captain- Here's where I'm a little confused. If the American market truly is saturated, or at least more mature, and they won't turn out for just anything, wouldn't it make sense that IF you are going to build a park, you had better build a park that stands out in some way, or at least gives your guests more of what they expect from you? Not just an big-budget park, but a park that will truly be a hit with your intended audience.
IoA had a lot of money thrown at it, but it's hard to figure out exactly who they are targeting. In the US, its the families that are the high margin guests, yet IoA has too many height restricted rides, and lacks the parades and shows that families love. They have enough thrill rides to bring in some day-trippers and thrill seekers, but they can't even match most Six Flags parks for pure thrills, and these are lower margin guests anyway. So they've got an expensive park that generally speaking is more suited to lower margin guests, but doesn't even go after them very well.
Disney on the other hand, is known as the premier family destination in the country. They have an in with this high margin segment, which is a part of the overall more discerning American market. So wouldn't it make sense that Disney's Anaheim strategy should be to build a high quality family park? Instead, they built a mid-quality park that is confused about who its trying to target. Not enough thrills to pull people away from Magic Mountain, but not enough Family Magic to get families to stay an extra day or two. But a TDS, or a similar type park is much more in line with what Disney guests want and expect. I'm not sure what the height restrictions are on its rides, but certainly the look and detail in the park are what would attract the families that Disney is looking for.
I'm not saying that just transplanting TDS in Anaheim would bring equal results, but I do believe it is much more in-line with what would work for Disney as a complement to DL in Anaheim. Yes, this would cost more money than DCA, but IF it were done with your target audience in mind, it really should work.
