Crown and Anchor Society points are determined by the length of your cruise and your choice of stateroom category. You will earn 1 point per night for each cruise in an interior, oceanview, or balcony stateroom and 2 points per night in a suite. For example, if you take a 7-night cruise in an interior stateroom, you'll earn 7 points. If you take the same 7-night cruise but book a suite, you'll earn 14 points. Royal Caribbean will occasionally run a promotion where you will earn double points for booking a cruise. These promotions are the best time to book if you want to quickly climb the membership tiers.
