I've never read anywhere that it is worth it to exchange points for a cruise anyway.
As an example I looked at the points chart for the 15 night Sydney to Honolulu cruise in 2024, and compared to the
DCL website cost.
The DCL website has the pricing right now for that cruise at $6,148.22 USD for 2 guests.
The points chart says 314-321 points per person based on double occupancy, for a standard inside room, so let's say 317 points x 2 = 634 points.
If you had 634 points and rented them to, say, the board sponsor, you're looking at around $15 per point, maybe a little more. That is $9,510 you could get for those 634 points, and of course, if you rented them yourself, you could potentially get a lot more. Effectively 1.5x the cost of paying cash, if you were to exchange points.
