The WDW version of Mermaid also has a big long mural along the load/unload belts. But the artwork shown has the loading area in sort of a rocky grotto that continues the rocky shoreline theme of the extended queue prior to the load/unload area. The clamshells appear to just go into a rocky outcropping in the grotto area to begin the ride.
The WDW version of the ride itself, once you take a seat in your clamshell, will be identical to the recently rehabbed and updated Disney California Adventure version.
Murals are OK . . . for hotels and restaurants, and older dark rides have them in the loading area, but the concept art for MK's loading area looks a lot better, at least as far as the shipwreck boat actually being in a seaside cave with the ocean out in the distance,
DCA's load area looks horribly fake a shipwreck next to a mural, and having ridden DCA's ride, believe me, the load area does nothing to "tell the story."
Let's hope that the MK version is nothing like DCA's, below is DCA's finale scene with the recycled turtle dancing the same way as his twins inside the Under the Sea scene, what a cheap way to end a ride,

I think even the Sebastian is the same! Check out Triton's eyebrows, they look like racoon tails, I guess we know what happened with those extra Davy Crockett coonskin caps they couldn't sell.
It just doesn't make sense, the sea animals should be waving to Ariel and Eric, who are out of view on the left and just got married, yet they are singing away to the beat of "Under the Sea" though the music here is different. They got really cheap! The turtle is the same, and the lobsters look familiar too! Sebastian looks like he is the same throughout the ride, conducting away . . .
Yup, the happy lobsters were duplicated for the finale, as was Sebastian! You can see him at the top here!
More duplicates, one of the "happy fish" heading to the Under the Sea scene is painted another color and looks way too happy to see Ariel get married, (here's green below at the beginning of the ride, and then turns purple for the wedding). That's right they were too . . . cheap to mold new fish that didn't look like they were laughing at Ariel! Oh! and I just noticed that the orange fish looks the same as in the beginning and end! I am guessing that only Ariel, Eric and Triton at original for the finale scene, everything else is an exact duplicate. WDI talked about not revealing the special ending, looks pretty cheap to me that they just recycled stuff, including the best animatronic in the scene, conductor Sebastian. OH, by the way, who in the world is he conducting? The idiotically dancing lobsters?
