SeaWorld Abu Dhabi isn’t going to have any whales buts it’s also not an iron park. It has a model of themed environments that could be exported to the US parks.
I personally would love to see this happen. I think they can have both amazing coasters and have highly themed environments.
Sea World does a lot to support conservation, and it's still called Sea World, which gives them the opportunity to do some really cool things to support that, engaging the public to care about the ocean and its inhabitants. Ending the orca breeding program isn't the end of all the other amazing things they do for sea life.
But they need to not just hire the right creative talent...they need to put the right amount of funding behind it and then maintain it. I think the general public would embrace it.
I keep thinking about Journey to Atlantis and wishing they committed to it.
