Today's Cruise News brief covers three developments across the cruise industry. Royal Caribbean's Harmony of the Seas returns to Europe for the first time in five years after an April to May 2026 drydock, sailing the Western Mediterranean from Barcelona and Civitavecchia before a July transatlantic crossing back to Port Canaveral, with roughly 100 new staterooms and refreshed onboard venues. MSC Cruises expands its Aurea Spa concept across its 23-ship fleet beginning summer 2026, adding medical-wellness services such as IV therapy, aesthetic injectables, AI-supported skin diagnostics, and a Japanese-inspired head spa. And Celestyal Cruises adds Agios Nikolaos, Crete as a regular call on its seven-night Idyllic Greece itinerary, replacing Heraklion, with an inaugural visit on May 12, 2026 and 28 annual calls planned.
