(9:39 a.m. EST) -- Carnival Cruise Line is expanding its staggered check-in program, where passengers receive an assigned time to board, through 2017. Between January and April, six more home ports will implement the embarkation procedure.
Tampa, Port Canaveral, San Juan, Vancouver and Seattle are the latest ports to begin the process. Ports that already have staggered check-in include Baltimore, Barcelona, Charleston, Fort Lauderdale, Galveston, Honolulu, Long Beach, Miami, Mobile, New Orleans, New York and Norfolk.
Tampa is the first to begin, with Carnival Pride on January 15. Port Canaveral will have three ships begin staggered check-in on January 26, January 28 and January 29. San Juan will start on January 22.
The embarkation process will change in Vancouver on April 30 and in Seattle on May 8.
Carnival began staggered embarkation in late 2015, as a way to make the boarding process more manageable.
