How far in advance can you book a Carnival cruise?
Just like with airlines and hotels, you can book your Carnival cruise months in advance. In fact, Carnival sometimes releases its itineraries over two years beforehand, giving travelers more opportunities to plan and budget for their vacation.
Although you don't have to rush to make your next cruise booking this minute, there are benefits to planning in advance. For example, you'll have more cabin options than if you were to look at a last-minute Carnival cruise.
