Harmony of the Seas is not strictly "all-inclusive," but rather follows a "mostly-inclusive" model where your base fare covers a significant portion of your experience while leaving premium options as extra-cost add-ons. Included in your fare are your accommodations, entertainment (such as Broadway-style shows and AquaTheater performances), access to most pools and the fitness center, and meals at several venues like the Main Dining Room, Windjammer Marketplace (buffet), and Sorrento’s Pizza. However, you will pay extra for "specialty dining" at venues like Chops Grille or Wonderland, as well as for alcoholic beverages, specialty coffees, and canned sodas. Other common extra charges in 2026 include the "Voom" high-speed Wi-Fi, spa treatments, certain fitness classes, and shore excursions. To make the experience feel more like a traditional all-inclusive, many guests purchase a "Deluxe Beverage Package" and a "Specialty Dining Package" in advance. While the sheer variety of free activities ensures you can have a great vacation without spending an extra dime, most travelers should budget for the "Daily Gratuities" and service charges that are automatically added to the final bill.
