I have some thoughts on this.
I love DAK. It is my favorite WDW park. Just to be there in the morning, get coffee, and walk through the different lands is satisfying for me. My deal with my wife is that we must do at least one animal trail every visit. And the safari might still be my favorite attraction in all of WDW, mainly because it is always a different experience each time you ride it.
Here is the issue that Disney will always struggle with in regard to this particular park. There are not a lot of rides because of all of the on stage and back stage animal attractions and care facilities. That will always cut down the number of actual rides in this park as they maintain this balance of rides/shows and animal-based attractions.
The animal trails and the safari close at sundown, neutering the park experience into the evening. Attendance numbers show how most people, vacationing to WDW, go to the other parks more. This tells me that the masses really want more rides over more animals.
To increase park attendance historically, Everest was added initially. Then years later Pandora was added. Neither EE or Pandora are about animals, as you put it. But both really helped drive attendance to this park. If they want to keep this park competitive in the Orlando market, they most likely will not be adding actual animal content, at least for now. They want to boost this park’s attendance on a constant and consistent basis. Adding animals - aside from Bluey - is something they don’t feel will do this. Adding known, proven content like the Madrigals and Indy, most likely will. And it helps that all the attractions in TA will be covered or indoors, and can stay open at night. What this park doesn’t need right now is another land where half of the experience closes at night because of the animals. It is an unfortunate reality. I want more animals too but I fear the very thing that the park is centered on prevents it from truly flourishing. Compromise is needed, and another shot in the arm attendance-wise. I believe this will accomplish that. It is current leaderships best compromise - a non-IP land and town where the Imagineers can play a little bit, populated with content that will really help drive attendance, that in the long run should help sustain this park.
