Out of curiosity and amusement I checked cabin availability for this sailing using 2A. Interesting how the least and most expensive sell out first.

Of course this is using the
DCL site and inventory can change hourly , so ....
Inside cat 10a; gone
Inside cat 11c; GTY
Inside cat 11b; 1 cabin left
Inside cat 11a; 3 cabins left
So 4 inside cabins left, wow.
OV cats gone; 8a-d, 9a
OV cat 9d; 1 cabin left
OV cat 9c; GTY
OV cat 9b; GTY
So 1 OV cabin left, wow.
Cat 4 - 7 verandas.
Cat 7; gone
Cat 6; gone
Cat 5e; gone (greedy folks here,

)
It shows at least 8 cabins in each of the other veranda cats, 5a-d, 4a-e, which is the max. So good availability.
CL cat V; gone
CL cat T; one left, 11020
CL cat R; gone
So top, bottom, and aft filling up, the middle yet to go.

I can now see why some don't know their cabin #. They booked GTY, IMO.
