What This Means
At 800, the top mix is still mostly Interior - GTY and Oceanview - GTY, but Balcony - GTY is already present. More importantly, Alaska is strong enough at the same tier that Europe is not competing with a single isolated premium sailing. It sits inside a broader, usable tier.
If you want Europe with better cabin access, 1,200 is the next step. But for a practical unlock, 800 is the first tier where Europe is clearly on the board.
