But that's nothing to do with this
Just because some of the PR material that has been released in the past has overstepped the line doesn't mean that the park should be attacked every time they try to put themselves into the public eye. Quite frankly, if those are the only stunts that you remember, mention or credit the park for it implies that these are the PR stunts that actually work.
So, instead, I would recommend attempting to ignore those stunts that offend you, as best you can, and credit the park over those that are actually reputable. That's the only way they'll learn. It's a business, it'll run with whatever gets noticed most.
