>>> the carnival cruise ship "triumph" is ready to sail again today after the engine fire that left thousands of passengers strand the at sea. nbc's janet shamlian is in galveston on the ship this morning.
>> reporter: the last time we saw triumph, these ships were filled with mattresses. they'd been dragged out here by very angry passengers, who were sleeping outside to avoid the stench in their room. it's been four months, and now carnival is unveiling what it says is a completely rehabbed triumph, even allowing us to broadcast live this morning just hours before it sets sail for the first time since that fateful cruise. today carnival hopes to erase the story of the old carnival "triumph" with a newly refurbished, and they say, much better carnival "triumph."
>> we're very excited, and we're here to have fun.
>> reporter: hobbled in february by an engine fire that left it adrift for almost a week, it was a nightmare. food in short supply. urine soaked the floors.
>> this is honestly the worst experience ever.
>> reporter: in the age of social media , the horrors played out before an audience of millions as passengers tweeted out photos and called in firsthand reports.
>> the worst part is the bathrooms. there's no water. you can't really flush. so everyone's going in little plastic baggies and putting it outside their rooms.
>> never with carnival. never again.
>> reporter: finally, the ship docked in mobile, alabama, the cruise line vowing "triumph" would be back. today it's a soldout crowd. cruises were discounted.
>> our pricing has been impacted some as a result of what happened.
>> reporter: now the ceo is touting millions of dollars in upgrades. a reputation makeover is also in the works.
>> is the main pool area, this entire area has been completely redone.
>> reporter: more serene scene than "triumph's" last cruise where many slept at night to escape the ship's stench and heat. for passengers sailing today, there's little concern.
>> i have full confidence in the repairs and upgrades that they've conducted.
>> reporter: so this is a really discounted cruise today. it's a four-day cruise to mexico . monday there's another five-day cruise to mexico , both of those sold out but at very discounted prices, and the cruise line is showing its ceo. he's out giving tours as well. they're definitely working on an image makeover as well. savannah, back to you.
>> janet shamlian , we'll see if you get off the boat before it heads to mexico . thank you so much.
