Carnival Miracle Alaska, Hawaii tweaks as tech glitch slows top speed

Carnival Cruise Lines said all the ship's safety and hotel systems are operating normally, and repairs are scheduled to be completed during an early 2015 drydock.

Until then, the technical issue has resulted in the reduction of Carnival Miracle's maximum cruising speed from 21 knots to 18 to 20 knots, depending on wind and sea conditions.

On the May 6-13 Alaska cruise, Sitka will replace the scheduled call at Skagway.

On sailings May 20 through Aug. 26, the Ketchikan call will be dropped and the calls at Juneau and Victoria, BC, will be extended.

On the Sept. 18 Hawaii cruise, a 16-day voyage, the scheduled two-day call at Maui will be shortened to one full day/evening call and the port sequence will be changed. All the scheduled Hawaii ports will be offered.

The April 28 and Sept. 2 Alaska itineraries will not require changes. The port sequence will change for the Sept. 10 itinerary, but all the scheduled ports will be offered. In addition, the current Hawaii cruise that sailed from Los Angeles April 12 is operating as scheduled.

Passengers on the May 6 through Aug. 26 cruises and the Sept. 18 cruise will receive a $50 per person on-board credit and a 25% discount on a future cruise. Those who wish to cancel will receive a full refund.
