Check dates of travel, names, birthdates, etc. -
Review your booking to make sure that you are on the correct ship leaving from the port you selected - on the date you wanted. Errors can be made and the sooner detected the better. Also, check to make sure names and birthdates appear on the booking exactly as they do on your passports. Name changes may result in additional fees to correct and failure to have matching documents may result in being denied boarding.
