The new ship sets sail as the industry works to lure customers back after a 15-month shutdown during the COVID-19 pandemic.
The Cruise Lines International Association estimates it could take until the end of 2023 for passenger volume to surpass the levels of 2019, when 29.7 million people boarded ships around the world.
The U.S. Centers for Disease Control and Prevention still advises that COVID-19 "spreads easily between people in close quarters on board ships" and that even vaccinated passengers may become infected.
D'Amaro said he believed Disney's cruise line would return to full capacity, noting steady gains in bookings.
"When all is said and done, we'll have seven of them, and all seven of them will be filled out," he said in an interview. "I have 100% confidence in that."
The ship also "complements everything that we do," D'Amaro added. "For example, people that will come to get aboard this ship ... they're spending three days at Walt Disney World."
The company will seek to entice vacationers to the Disney Wish with what it touts as its first attraction at sea, the AquaMouse. The theme-park-like ride incorporates animated short films featuring Mickey and other characters as guests float through 760 feet (230 meters) of winding tubes suspended above the upper decks.
Dining experiences place families inside the worlds of Disney's "Frozen" and Marvel's Avengers. For adults, Disney created a Star Wars-themed hyperspace lounge that evokes the look of star cruisers in "Solo: A Star Wars Story."
The ship also boasts an interactive experience that marries the physical and digital worlds. A Disney Cruise Line app turns a user's phone into a virtual "spyglass" for peering at constellations in the night sky (which appear as Disney and Pixar characters) and embarking on adventures.
The interactive game marks a step toward Chapek's goal of establishing a presence in the metaverse. The executive has advocated virtual experiences as a way to keep consumers connected to Disney characters and stories in between movie releases and park visits.
The Disney Wish will set out on its first voyage on July 14 from Port Canaveral in Florida.
