I honestly think it boils down to timing. Orlando locks in the entirety of their event much earlier than Hollywood does (see Obsession appearing in Hollywood and not Orlando). From my understanding, Fortnitemares was the last IP to get secured. Zones are normally last to get developed, but securing an IP zone “late” (March) can really cause issues for Orlando’s design team. Remember, Orlando is bigger than Hollywood and starts earlier. A single late change can have significant impacts on the rest of the event. And that includes food. (This is also why I think the Fortnitemares merch isn’t has complicated as the other IPs.)
Now, do I think they could have renamed a couple of things and redesigned one booth for Fortnitemares? Theoretically. But which one do you replace? Is the booth in CP equipped for the most “Fortnite-esque” food? If it’s not, what does that do.
Basically, Orlando was probably too far ahead in all of its planning for this year to best integrate Fortnitemares. Hollywood is way more flexible.
