"As soon as you get them calmed down, the electric goes out and doors start slamming shut," he said.
During less stressful times, passengers passed the hours playing cards, walking the deck and going to see what was happening on other areas of the ship, Poret said.
Passengers set up charging stations to help their fellow passengers juice up cell phones and other devices, he said.
The final trip home
Carnival promised an army of about 200 employees would take care of its passengers once they cleared customs.
Passengers boarded buses to Galveston, where the cruise originated, or Houston, or went to spend the night in a hotel in New Orleans.
Carnival said it had reserved about 100 motor coaches, more than 1,500 New Orleans hotel rooms, multiple charter flights from New Orleans to Houston on Friday and transportation from Houston to the Port of Galveston so that guests may retrieve their cars if they drove to the port.
Carnival officials had initially planned to tow the ship to a Mexican port, but after Gulf currents pushed it farther north before tugboats could take control, and considering that 900 of the passengers do not have passports, the company decided to take the Carnival Triumph to Mobile instead, where it can be repaired.
Compensation for travelers
The cruise line said it would give each passenger $500, a free flight home, a full refund for their trip and for most expenses on board, as well as a credit for another cruise.
The Coast Guard and the National Transportation Safety Board launched an investigation into the cause of the engine room fire. Because the Carnival Triumph is a Bahamian-flagged vessel, the Bahamas Maritime Authority is the primary investigative agency.
Travelers have few options for compensation in these cases, other than what the cruise line is already offering, according to travel expert Jason Clampet of Skift.com, a travel website.
"The passengers on the ship aren't going to have a great deal of recourse when they get home," he said. Travel "insurance really doesn't cover this sort of thing. Their trip wasn't interrupted and they aren't incurring extra expenses ... so they can't be compensated that way."
Still, there's no denying that the fire and resulting bad PR will hurt Carnival.
"It's a terrible sight, thinking of people trapped on a ship with limited food and filthy conditions, so I think people will think twice about taking a cruise," Clampet said.
Bad luck before
The fire is at least the second problem for the ship since late January, when it had an issue with its propulsion system, according to a notice posted on the website of Carnival senior cruise director John Heald.
It's also not the first fire to disable one of the cruise line's ships.
In 2010, the Carnival cruise ship Splendor lost power after an engine room fire, leaving it drifting off the Pacific coast of Mexico. The USS Ronald Reagan ferried 60,000 pounds of supplies for the ship's passengers and crew as the ship was towed to San Diego.
After this ill-fated cruise, the Carnival Triumph won't host vacationing passengers until at least mid-April. Carnival has canceled a dozen voyages scheduled between February 21 and April 13. That makes a total of 14 scratched trips. The cruise line already had eliminated voyages slated for February 11 and February 16.
