On Friday, the company said a technical issue with one of the ship’s thrusters is affecting the sailing speed of the Legend, forcing the cancellation of a stop at the Grand Cayman Islands. The ship is expected to arrive in Tampa as scheduled Sunday following a seven-day cruise. Passengers will get a $100 credit, refunds on pre-paid shore excursions and half off on a future cruise. Also this week, the Carnival Dream experienced problems with an on-board generator while docked in St. Maarten. Passengers are being flown home. A month ago, passengers on the Carnival Triumph spent five days in the Gulf of Mexico without power or working toilets.
