The 2001-built Adventure of the Seas will emerge with the changes in November.
Dual racer waterslides Cyclone and Typhoon, a FlowRider surf simulator and children's water park Splashaway Bay are joining the open deck features.
New culinary and entertainment venues will include Izumi Japanese Cuisine, Royal Caribbean's signature steak house, Chops Grille, and Boleros Latin Lounge.
Along with adding 100 accommodations, the refurbishment will refresh existing staterooms and install a Suites Lounge.
Adventure of the Seas sails from San Juan, Puerto Rico, to southern Caribbean destinations including Bridgetown, Barbados; Castries, St. Lucia; St. Johns, Antigua; Basseterre, St. Kitts; and Philipsburg, St. Maarten.
