After five days without power in the Gulf of Mexico, the more than 4,200 people aboard the Carnival Triumph returned home to the U.S., with many of them telling their horror stories for the first time.

Passengers began to disembark the damaged ship around 10:15 p.m. CT Thursday in Mobile, Ala. The last passenger disembarked the ship at 1 a.m. local time, according to Carnival's Twitter handle.

Passenger Brandi Dorsett was thankful to be home, especially for her mother, who was with her on the ship. Dorsett said she wasn't pleased with the doctor on staff.

"My mother is a diabetic, and they would not even come to the room because she cannot walk the stairs to help her with insulin. She hasn't had insulin in three days," Dorsett said. (MORE AT ABCNEWS.COM)
