Navigator of the Seas underwent an extended dry dock at Seatrium's Singapore facility from February 16 through April 6, 2024. The project focused on routine machinery overhaul, classification work, minor repairs and steel work, together with hotel and interior updates. Passenger staterooms and public areas received refreshed carpeting, upholstery and wall treatments.

Navigator of the Seas underwent an approximately $115 million Royal Amplified modernization in 2019. The project introduced a completely reimagined Caribbean-style pool deck, The Lime & Coconut, The Perfect Storm waterslides and The Blaster aqua coaster. New and reworked venues included The Bamboo Room, Playmakers Sports Bar & Arcade and To Dry For, Royal Caribbean's first standalone blow-dry bar at sea. Adventure Ocean and other passenger areas were also redesigned as part of the extensive shipwide refurbishment.
