rendering of Celebration Key with cabanas, pools, buildings
Carnival says its private Celebration Key destination will have a family-friendly section with amenities like two waterslides, a water playground, and rentable cabanas.
  • Carnival Cruise Line is set to launch its new private destination, Celebration Key, in 2025.
  • The $600 million project has amenities similar to Royal Caribbean's private island.
  • Carnival is "clearly following Royal Caribbean's footsteps," one analyst told Business Insider.

Step aside, CocoCay. Royal Caribbean's private island could soon face some serious competition.
