Which dates usually sell out first for Alaska?

I cannot book until tomorrow, so a little worried.

I wouldn't worry. Only the unique itineraries sell out fast. DCL sails Alaska for the whole summer, so there is plenty of availability over the season. Things like the Hawaiian that only happen every few years are the only things that sell out in the first couple days. Unique rooms like secret porthole and navigators verandas may sell out quickly though.
