The Caribbean class cruise ships were developed as a one-off modification of the Grand Class specifically for Princess Cruises. Caribbean Princess introduced an extra deck of passenger cabins called the Riviera deck, significantly increasing capacity while keeping the core Grand Class layout. The ship features a unique family-focused pool deck with a dedicated splash pool and water play area that distinguishes it from other Grand Class sisters. The class was optimized for longer Caribbean itineraries with enhanced children's facilities and family-oriented public spaces.
