In a statement on the Carnival Cruise Lines website, Gerry Cahill, President and CEO of Carnival Cruise Lines said: "We know it has been a longer journey back than we anticipated at the beginning of the week under very challenging circumstances.
"We are very sorry for what our guests have had to endure. Therefore, in addition to the full refund and future cruise credit already offered, we have decided to provide this additional compensation. I look forward to welcoming everyone to Mobile."
