ALABAMA - The nightmare is over for more than 4,000 cruise ship passengers who were stranded at sea for a week.

Passengers of the Carnival Triumph waved signs saying "Sweet Home Alabama" as their crippled ship was towed to Mobile overnight.

There were cheers as the nightmare cruise in the Gulf of Mexico finally ended.

Passengers struggled without working bathrooms, sewage seeping down walls and little food.

Officials say trouble started after an engine room fire Sunday.

Carnival has now cancelled about a dozen more voyages on the Triumph.

The NTSB is investigating the ship's problems.
