Cruise lines are trying to get smarter about the kind of retail they have on board and how they get passengers engaged with the shops. As travelers crave more meaningful experiences during their vacations, where does that leave cruise ship shopping? Cruise operators are trying to figure that out and deliver the kind of retail that passengers will respond to. For example, Carnival Horizon will include two decks of shops including a Victoria’s Secret boutique, a space devoted to wearable gadgets, and a beauty bar. Carnival, which is part of cruise giant Carnival Corp., has renovated shops on four older ships in the past year, and plans to redo four more in 2018 to include more interactive experiences.
