"Changes at the margins" is a direct quote of Tom Staggs.
Here are some more direct quotes from Tom Staggs and additional exerpts of what he said from the same article you have cited:
“We took a hard look at it amongst a number of us and said, ‘Can we make the appeal broader? Can we make it even better?’
Staggs said much of what was included in the original plans will be incorporated into the final product and that the changes are “improving it on the margin.” He characterized the revisions as part of any creative project’s natural evolution. As an example, Disney cited Hong Kong Disneyland, where early blueprints included an area dubbed “Glacier Peak” that was eventually replaced with a section themed around the company’s Toy Story film franchise
“One of the things that I thought the early design did fantastically was delivered on that princess experience. And that does tend to skew towards girls. … We’ve kept that intact — not exactly, necessarily, the way it was presented, but that appeal is there,” Staggs said. “I think we’ve added some things that aren’t just princess-focused, and that’s a good positive.”
Staggs said planners are also reviewing the Fantasyland expansion with an eye toward blending “aspirational rides” — rides that offer thrills or tension — with attractions designed for guests of all ages. And he said they want to ensure that the additions are flexible and can be updated or adapted over time.
Staggs said the project’s price tag will “not materially” change with the revisions, though a slight increase is likely because of certain additions. He would not provide specific figures
So while you chose to cling to one phrase from the article and use it out of context, the rest of us choose utilize information from the entire article to draw our conclusions. The conclusion which can be drawn from these quotes are as follows, with a few questions:
-Something will be added to the original design which makes it better and broadens the appeal.
-As a part of the revision, a ride will be built that provides family friendly thrills.
-If assuming the "on the margin" additions are not referring to any attraction (although the article directly disproves this notion anyway), then what can be added that is not princess focused and will broaden the appeal significantly enough to warrant a revision and consider the revision to broaden anything? Also, when speaking of the aforementioned revisions "on the margin", an example was given of an entire land being changed for the Hong Kong expansion.
-If the fantasyland expansion at least includes a BatB counter service and elaborate sit down restaurant, the little mermaid ride, circusland with dumbo, and maybe one of the previously mentioned meet and greets, then could one additional attraction be considered "on the margin" relative to the rest of the area?
-Whatever is being added may cost a little more than what is being removed (rumored to be some meet and greets and pixie hollow, which would have to make it relatively big).
-At least one thing that was added still involves a princess but does not nessisarily focus on said princess :animwink:
It also seems that there may be a little more than what we are currently expecting since multiple changes are referenced.
