What This Means
The 600-point Alaska option is limited, but it is real. It is also the first two-guest offer in the release, which gives it extra importance for lower-tier players. The sailing count at 600 is only 34, so this is not a broad Alaska tier. It is a single-entry point.
The next step up is 800 points, where Alaska becomes more usable. That tier adds multiple Alaska sailings, including Ovation of the Seas on a Southbound Hubbard Glacier Oceanview and Voyager of the Seas on Alaska Experience itineraries from Seattle. If the question is when Alaska becomes practical rather than merely available, 800 is the better answer.
So the threshold is 600 for access, but 800 for real choice. This month, Alaska starts early.
