What This Means
It has only 55 sailings, all in Interior - GTY. That makes it the narrowest tier on the board by a wide margin. The region mix is also limited: 27 Mexico sailings, 26 Caribbean sailings, and 1 Alaska sailing.
The best cruise is Serenade of the Seas, 7 Night Cabo Overnight, Catalina & Ensenada, departing San Diego on 2026-12-13. It scores 90.5 and is a Cruise Fare For 1 Guest offer. That is a workable offer, but it is not enough to make the tier broadly competitive with the rest of the release.
The issue is not that the tier is unusable. The issue is that it is too constrained. It lacks cabin variety, it lacks destination variety, and it does not participate in the free-play ladder at all.
By comparison, the 600 and 800 tiers open more sailing count and more itinerary flexibility, while still staying close to the low end of the board. If you are looking for the first tier that feels like a real choice set, 400 is not it.
This tier is best treated as a narrow entry point, not a value target.
