Cabins and suites. Royal Caribbean offers a dizzying array of cabin and suite options, especially on its newest and largest ships. Celebrity features fewer overall cabin categories but offers non-suite rooms that come with extra perks. Both cruise lines offer a variety of cabin styles and price points.

While both are owned by the Royal Caribbean Group, they offer vastly different "vibes" in 2026. Royal Caribbean is a "contemporary" line focused on the "wow factor" and family adventure, featuring massive ships with water slides, ice rinks, and "Robot Bars." It is the go-to for families with children. Celebrity Cruises is a "premium" line that targets a more sophisticated, adult-oriented demographic (median age 40s–50s). In 2026, Celebrity's "Edge Class" ships focus on high-concept design, fine dining, and "The Retreat"—an exclusive suite-class experience. While Royal Caribbean emphasizes "doing," Celebrity emphasizes "being," with a focus on wellness, trendy spa experiences, and a much higher crew-to-guest ratio for personalized service. You won't find water slides on a Celebrity ship; instead, you'll find rooftop gardens and martini bars with "flair" bartenders. Essentially, choose Royal Caribbean for a high-energy family reunion and Celebrity for a chic, modern romantic getaway or a luxury food-and-wine-focused vacation.
