To reach the Diamond Plus tier in Royal Caribbean's Crown & Anchor Society, you must accumulate a total of 175 cruise points. In this loyalty system, you earn one point for every night you sail on a Royal Caribbean ship. However, you can accelerate your progress by booking higher-tier accommodations; guests staying in suites earn two points per night, and solo travelers staying in a double-occupancy cabin while paying the single supplement also receive double points. The transition from the Diamond level (which requires 80 points) to Diamond Plus is significant, as it unlocks a higher level of "onboard recognition." Key benefits at 175 points include increased discounts on beverage packages, five daily complimentary drink vouchers (up to $14 each), and access to the dedicated Diamond Lounge. Once you surpass the 170-point mark, you enter a "milestone" phase where you can receive personalized amenities and priority seating at theaters. Reaching Diamond Plus is a major goal for frequent cruisers as it represents the final tier before the elite "Pinnacle Club" status, which requires a much steeper 700 points.
