• Redeem an initial 180,000 points toward a $1,000 savings on your cruise fare, and increments of 90,000 points toward a $500 savings thereafter

This is a value of 0.55 cents per point (less after opportunity cost). The last time Marriott provided a value of points was Homes & Villas where they nerfed it from 0.7 to 0.6. Possibly relevant for future dynamic pricing
