Carnival Will Pay Unhappy Passengers to Abandon Ship Cruise line offers refund plus 10% in first 24 hours of trip By John Johnson, Newser Staff Posted Sep 13, 2013 3:21 PM CDT 15 comments Comments File photo of a Carnival ship. (AP Photo/Dave Martin, File) (Newser) – Carnival Cruise Lines has had some foul-smelling publicity of late, and the company hopes to fix that with an unusual offer to passengers: If they immediately hate the cruise they're on, the company will refund their fare plus 10%, reports the Houston Chronicle. Passengers will be put aboard a plane home, and Carnival will cover that and all other related travel expenses. On the odd chance they'd like to try again, they'll get a $100 credit for a future trip. The one catch is that passengers must notify the crew they want off the ship within the first 24 hours.
