MOBILE, Ala. The passengers of the Carnival cruise ship Triumph began the process of getting back to normal early Friday, checking into hotels for a shower, hot meal and good night's sleep or boarding buses bound for other cities after five numbing days at sea on a powerless ship disabled by an engine-room fire.
The cruise ship carrying some 4,200 people finally docked late Thursday in Mobile, as passengers raucously cheered the end to an ocean odyssey.
"Sweet Home Alabama!" read one of the homemade signs passengers affixed alongside the 14-story ship as many celebrated at deck rails lining several levels of the stricken ship.
The ship's horn loudly blasted several times as four tugboats pulled the crippled ship to shore at about 9:15 p.m. CST. Some passengers gave a thumbs-up sign, and flashes from cameras and cell phones lit the night.
Nearly four hours later, the last passenger had disembarked.
Some, like 56-year-old Deborah Knight of Houston, had no interest in boarding one of about 100 buses assembled to carry passengers to hotels in New Orleans or Texas. Her husband, Seth, drove in from Houston and they checked into a downtown Mobile hotel.
"I want a hot shower and a daggum Whataburger," said Knight, who was wearing a bathrobe over her clothes as her bags were unloaded from her husband's pickup truck. She said she was afraid to eat the food on board and had gotten sick while on the ship.
To add insult to injury, at least one of the chartered buses became stranded on the way to New Orleans, correspondent Anna Werner told "CBS This Morning." Passenger Jacob Combs called CBS News en route to say his bus was sitting by the side of the road, as he waited for yet one more rescue.
As buses arrived in the pre-dawn darkness at the Hilton in New Orleans, paramedics were on the scene with wheelchairs to roll in passengers who were elderly or too fatigued to walk.
Many were tired and didn't want to talk. There were long lines to check into rooms. Some got emotional as they described the deplorable conditions of the ship.
"It was horrible, just horrible" said Maria Hernandez, 28, of Angleton, Texas, tears welling in her eyes as she talked about waking up to smoke in her lower-level room Sunday, and the days of heat and stench to follow. She was on a "girls trip" with friends.
She said the group hauled mattresses to upper-level decks to escape the heat. As she pulled her luggage into the hotel, a flashlight around her neck, she managed a smile and even a giggle when asked to show her red "poo-poo bag" -- distributed by the cruise line for collecting human waste.
This was only part of her journey to get home. Hernandez, like hundreds of others, would get to enjoy a brief reprieve at the hotel before flying home later in the day.
"I just can't wait to be home," she said.}
It wasn't long after the ship pulled into the Port of Mobile that passengers began streaming down the gang plank, some in wheelchairs and others pulling carry-on luggage. One man gave the thumbs-up.
An ambulance pulled up to a gate and pulled away, lights flashing.
Carnival had said it would take up to five hours for all the 3,000 passengers to be off. It took closer to four.
"All guests have now disembarked the Carnival Triumph," Carnival tweeted.
Carnival hasand 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.
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.
In texts and flitting cell phone calls, the ship's passengers described miserable conditions while at sea, many anxious to walk on solid ground.
Passenger Jacob Combs told CBS News via phone: "The really bad part is there was no running water and toilets for almost the first 30 hours. Once they finally did get running water, the toilets only worked in certain places. I would say it's the worst smell imaginable."
Emailed photos reveal squalid conditions. Many passengers used red plastic bags as toilets. Hundreds slept in hallways or topside to escape the foul and stagnate air below deck.
Carnival CEO Jerry Cahill insists passengers were never at risk. But 22-year old Leslie Mayberry disagreed.
"It was leaning to one side, it was literally like walking up hill whenever the boat was leaning," she said. "I mean, it was very scary," Mayberry said. "A lot of people thought it was going to tip over and sink. And then you look out on the deck and you see the ocean and there is no one, you are just by yourself and you are so alone, even though you are around 3,000 other people on this boat."
For 24-year-old Brittany Ferguson of Texas, not knowing how long passengers had to endure their time aboard was the worst part.
"I'm feeling awesome just to see land and buildings," said Ferguson, who was in a white robe given to her aboard to weather the cold nights. "The scariest part was just not knowing when we'd get back."
As the ship pulled up, some aboard shouted, "Hello, Mobile!" Some danced in celebration on one of the balconies. "Happy V-Day" read one of the homemade signs made for the Valentine's Day arrival and another, more starkly: "The ship's afloat, so is the sewage."
A few dozen relatives on the top floor of the parking deck of the terminal were waving lights at the ship as it carefully made its way alongside. Those about were screaming, whistling and taking pictures.
Hundreds gawked from dockside at the arrival at the Alabama cruise terminal in Mobile, the state's only seaport, as the Triumph docked.
Taxis were lined up waiting for people, and motorists on Interstate 10 stopped to watch the exodus of passengers from the cruise ship.
Some still aboard chanted, "Let me off, let me off!"
It took six grueling hours navigating the 30-odd-mile ship channel to dock, guided by at least four towboats. Nearly 900 feet in length, it was the largest cruise ship ever to dock at Mobile.
Galveston is the home port of the ill-fated ship, which lost power in an engine-room fire Sunday some 150 miles off Mexico's Yucatan peninsula. It was the end of a cruise that wasn't anything like what a brochure might describe.
Carnival's Cahill apologized at a news conference and later on the public address system as people were disembarking.
"I appreciate the patience of our guests and their ability to cope with the situation. And I'd like to reiterate the apology I made earlier. I know the conditions on board were very poor," he said. "We pride ourselves on providing our guests with a great vacation experience, and clearly we failed in this particular case."
Passenger Ferguson said crew members tried to make the situation bearable.
"They did their best to keep our spirits up," she said.
Joseph and Cecilia Alvarez of San Antonio said some passengers passed the time by forming a Bible study group.
"It was awesome," he said. "It lifted up our souls and gave us hope that we would get back."
While the passengers are headed home, Triumph will head to a Mobile shipyard for assessment.
Earlier Thursday -- four days after the 893-foot ship was crippled in the middle of the Gulf of Mexico -- the passengers and crew suffered another setback with towline issues that brought the vessel to a dead stop for about an hour just as it was getting close to port.
As the vessel drew within cell phone range Thursday, passengers vented their anger.
In a text message, Kalin Hill, of Houston, described deplorable conditions over the past few days.
"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."
She said, "There's poop and urine all along the floor. The floor is flooded with sewer water ... and we had to poop in bags."
The company disputed the accounts of passengers who described the ship as filthy, saying employees were doing everything to ensure people were comfortable.
Kendall Jenkins of Houston won her first cruise as a contest prize. But she's never planning to set sail on a cruise again after the ill-fated voyage of the Triumph, despite the offer for another free cruise.
"This is my first and last cruise. So if anyone wants my free cruise, look me up," said Jenkins, 24.
She and her friend, Ferguson, bounded off the ship Thursday night clad in bathrobes. They immediately kissed the pavement at the Port of Mobile, having spent their final minutes aboard jumping up and down excitedly.
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."
