What This Means
The best sailing is Serenade of the Seas on a 7 Night Pacific Coastal Cruise out of San Diego, with a score of 79.5. That is a decent itinerary for the tier, but it is still a one-guest cruise fare offer and the overall selection is thin. The rest of the tier is a mix of short Caribbean and Mexico sailings, with no real cabin spread and no meaningful premium upside.
Compared with the rest of the certificate, 400 points is the least useful tier because it lacks both volume and variety. The 600 point tier is still small, but it already opens Alaska. The 800 point tier adds more region coverage and starts to show oceanview and balcony GTY inventory. By contrast, 400 points stays boxed into interior fare-only offers.
For readers trying to find the first usable step in the certificate, 400 points is not it. It is the floor, not the entry point.
