"The lower floors had it the worst, the floors 'squish' when you walk and lots of the lower rooms have flooding from above floors," Hill wrote. "Half the bachelorette party was on two; the smell down there literally chokes you and hurts your eyes."
Shanar said passengers initially were given only cold cuts, such as turkey and vegetable sandwiches. Then another cruise line dropped off hamburgers and chicken sandwiches, but the line for that fare was nearly four hours long, she said.
"There's poop and urine all along the floor," she said. "The floor is flooded with sewer water ... and we had to poop in bags."
The 14-story ship still must negotiate a tricky, shallow shipping channel, and was expected to be the largest cruise liner to ever dock in Mobile. The channel narrows to 400 feet inside Mobile Bay, and the ship was only 115 feet wide. It was traveling about 5 mph.
The company disputed the accounts of passengers who described the ship as filthy, saying employees were doing everything to ensure people were comfortable. Carnival didn't immediately respond to questions the illnesses reported by some passengers.
Terry Thornton, senior vice president for Carnival Cruise Lines, said the ship received an extra generator that allowed hot food to be served.
"This is going to be a long day," Thornton said Thursday. "There is no way we can speed up the process."
Some travel agents said cruise prices and bookings have not been affected by the disabled Carnival ship, but others in the industry say it's too early to tell.
Thelbert Lanier was waiting at the Mobile port for his wife, who texted him early Thursday.
"Room smells like an outhouse. Cold water only, toilets haven't work in 3 1/2 days. Happy Valentines Day!!! I love u & wish I was there," she said in the text message, which was viewed by The Associated Press. "It's 4:00 am. Can't sleep...it's cold & I'm starting to get sick."
Carnival spokesman Vance Gulliksen said the company tried to keep families updated and established a toll-free number for friends and relatives. Gulliksen said about 200 Carnival employees were in Mobile waiting to assist passengers upon their arrival.
The ship was about 150 miles off Mexico's Yucatan Peninsula when an engine room fire knocked out its primary power source Sunday, crippling its water and plumbing systems and leaving it adrift on only backup power.
No one was injured in the fire, but a passenger with a pre-existing medical condition was taken off the ship as a precaution. In addition, the Coast Guard said in a statement Thursday that it evacuated a passenger who reportedly suffered a stroke.
Carnival said the original plan was to tow the ship to Progreso, Mexico, because it was the closest port, but by the time tugboats arrived, the ship had drifted about 90 miles north due to strong currents, putting it nearly equidistant to Mobile. It was also logistically easier for the company, which said costs were not a factor.
Carnival Cruise Lines has canceled a dozen more planned voyages aboard the Triumph and acknowledged the crippled ship had been plagued by other mechanical problems in the weeks before the engine-room blaze. The National Transportation Safety Board has opened an investigation.
Gulliksen said the Triumph's recent mechanical woes involved an electrical problem with the ship's alternator on the previous voyage. Repairs were completed Feb. 2, and the problem was not related to the fire, he said.
Passengers were supposed to get a full refund and discounts on future cruises, and Carnival announced Wednesday they would each get an additional $500 in compensation.
Once docked, the ship will be idle through April.
Passengers to receive refunds, credit for future cruise
Carnival said all of the passengers will receive a full refund for the cruise, along with transportation expenses. They'll also be reimbursed for all purchases aboard the ship, except for gift shop and casino charges. They will also received a future cruise credit equal to the amount paid for this voyage.
On Wednesday, Carnival officials said all passengers will also get $500 compensation.
"We know it has been a longer journey back than we anticipated at the beginning of the week under very challenging circumstances," Cahill said. "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."
Carnival cancels 14 voyages
Carnival Cruise Lines cancelled 12 additional voyages of the cruise ship Triumph on Wednesday.
The cancelled cruises, which include sailings from Feb. 21 through April 13, are in addition to two previously cancelled voyages departing from Galveston on Feb. 11 and Feb. 16.
Guests booked on the cancelled voyages will receive a full refund, reimbursement for non-refundable travel expenses and a 25 percent discount on a future three- or five-day cruise or a 15 percent discount on a six- to-seven day cruise.
