Which cruise ship introduced Royal Caribbean’s Central Park outdoor neighborhood?

Oasis of the Seas introduced Royal Caribbean’s Central Park outdoor neighborhood.

The ship entered service in 2009 as the first vessel in Royal Caribbean’s Oasis class. Its design divided the interior into themed neighborhoods, including Central Park, a landscaped open-air area with living plants, restaurants, shops, and public spaces.

Central Park is located in the middle of the ship and is open to the sky. It helped distinguish Oasis of the Seas from earlier cruise ships, which generally organized public rooms by decks rather than by large neighborhood concepts.

Allure of the Seas, Harmony of the Seas, and Symphony of the Seas also feature Central Park, but they followed the original Oasis. This makes Oasis of the Seas the correct answer when the question asks which ship introduced the neighborhood rather than which ships contain it.
