Even before my source weighed in on the matter with their own claims, it was all of that blatantly empty space in the renders that made me doubt the final scene will be so sparse. The ride's restaurant facade also isn't a copy of the one from the film, it is fully unique with a different design and all of those empty spaces are unique to the ride.
Here's what that facade looks like in the film-

Just the sidewalk and that one smallish balcony on the second floor. Now compare that to the brand new facade from SplashArchive's renders of the ride-

It's a completely different design for starters, which is already odd. And it comes with a lot of very suspicious new "empty" spaces. Assuming the positioning of the figures in the renders is close to final (and I find that to be relatively believable at least, aside from the t-posing which is yet also another indication that these may not be final), the bottom level would contain Tiana, Louis, Naveen and Ralphie. Then there's a large empty balcony on the second level, larger even than the movie's. But most of all, a bunch of staircases and landings wrapping around the sides that weren't in the film's variant at all and look deliberately designed to contain animatronics. In fact, these staircases and landings are remarkably similar to the riverboat in Splash Mtn which housed so many AA's.
It's just really difficult to imagine why they would go to the trouble to create all of these unique platforms that look deliberately designed to contain AA's, only to leave them empty... Even the large structure on the left side (formerly where the Swamp Boys were) is much larger than what was there prior and appears to contain a ton of extra space for additional AA's beyond just Eudora and Charlotte. Plus the space over to the right where the cart and its figures used to be at DL.
