Exactly attendance is up and so are profits so why add anything. But then there is universal where profits and attendance is up and they are adding big things.The poster above made a great point about the reason Carsland happened and renovations and new attractions at the foreign parks. Attendance keeps increasing in the FL parks, so why would they add new rides? I mean of course they should for the sake of trying to make DW the best it can possibly be and always innovating, improving, and adding, but from a strict business stand point they don't need to.
Someone said the difference between DL and DW is that DL is more of a locals park, the majority of the visitors to it live near it. So if they don't ever put in new rides, those people will be less likely to keep coming as much; whereas at DW it's primarily from visitors from all over the country and world. So for people who visit once a decade they're happy with what is there b/c it's been 10 years since they've been there. It definitely makes sense.
One thing I was thinking about is with there now being a Disney Park in Europe, Hong Kong, Japan, and now China, maybe some of the foreign visitors will no longer make the trip to Orlando to come to DW b/c they have a park closer to them. Additionally, with Universal now a top notch Disney alternative and other competitors really stepping up their game, maybe just maybe park attendance will slow down. If that happened maybe DW would be forced to build new attractions.
I for one had not been to DW in many years, I visited all four parks. I loved it but also realized how much more they need to build. When I go back to Orlando, I'll stick to the MK and then go to Universal. Any trips after that will be determined by what is new. If there is enough people like me then maybe attendance won't keep mindlessly increasing every year without improvements, maybe...
You're point about DL is partially correct. Disneyland hasn't seen any new major attractions since Indy. DCA was redone because it was losing money. DL does however add entertainment and other things all the time then you have the big 60th celebration this year that will be a huge money maker for them. WDW barely celebrates anniversaries.
In terms of foreigners DLP has been open for 20+ years and those people still come to WDW as well. Brazil is a big foreign component to WDW. China is a new market basically for Disney they are not well represented in that country.
