12 reasons to get as early a check-in time as possible for your cruise
Weeks before your cruise begins, you will have an important decision to make: when do you want to check-in for your cruise?
The online check-in process varies from cruise line to cruise line. Carnival's, for instance, opens up 14 days before your sail date, while Norwegian's opens 21 days prior and Royal Caribbean 45 days before.
During the process, each cruise line will ask you what time you would like to arrive at the port and begin the physical check-in process, which entails checking your travel documents and going through airport-like security.
