In DCA: The Little Mermaid - Ariel's Under Sea Adventure
In MK: Under The Sea - Journey of the Little Mermaid.
And with the exception of the queue, the rides are exactly the same.
DCA's problem is the rides are 3 words or longer, while Disneyland's rides are usually 2 words. What's wrong with calling it the Toy Story ride? Twilight Zone Tower of Terror is tongue twisting. Just call it Tower of Terror.
Disney's California Adventure is most wrongly named. Not only is it three words, it is three multi-syllable names. They had a chance to change it during the premiere of Carsland. It came and went. Call it Disney's Adventure.
As for DCA, I'd kinda like to see Disney go with the name "Disney's Hollywoodland" for DCA, DHS and Walt Disney Studios Paris. But I don't know that it could get the trademark.
"Journey into Imagination with Figment" should just be "Figment"
"Expedition Everest: Legend of the Forbidden Mountain" becomes either "Everest" or even "Expedition Everest"
"Harry Potter and the Forbidden Journey" should be "Harry Potter"
I think for some of the other rides, and this is just my opinion, is the "long ride title" is simply a way of making the attraction sound more exciting & enticing.
Looking at the examples listed by Anon & DPCC Inc, it's true, those ride names can easily be shortened. Spider-man, harry potter, toy story, Everest, Buzz Lightyear all work.
But I think by adding words like, "journey", "adventure", "legend" or other adjectives, it's meant to convey a specific feeling or objective.
Regarding Despicable Me, either PR folks think we need everything explaining... OR there's plans for tie-ins with The Minions Movie out next year, and those attractions could have similar names.
