Carsland is, without the slightest doubt, the best single IP land Disney ever built.
People forget examples like Mermaid Lagoon at Tokyo DisneySea because they predate the trend set by Wizarding World, but my vote goes to Mysterious Island from the same park. "Immersive" by any definition with two excellent rides instead of one great ride and then one or two side dishes.
Unless it doesn't count because it's not a super accurate recreation of any specific Verne novel and goes off script in adapting the 1954 Disney movie and mixing its sources.
Arabian Coast is also wonderful, and all the better for not just being "Aladdin Land" and drawing from a broader set of influences.
