(CNN) -- A month after a fire crippled a Carnival ship in the Gulf of Mexico, another one of the cruise line's vessels may be experiencing its own problems.
Multiple passengers aboard the Carnival Dream have contacted CNN, telling stories of power outages and overflowing toilets, all while docked in port at Philipsburg, St. Maarten, in the eastern Caribbean.
"We are not allowed off of the boat despite the fact that we have no way to use the restrooms on board," Jonathan Evans of Reidsville, North Carolina, said in an e-mail early Thursday. "The cruise director is giving passengers very limited information and tons of empty promises. What was supposed to take a hour has turned into 7+ hours."
The Dream was scheduled to leave port around 5 p.m. ET on Wednesday.
Gregg Stark, who is traveling with his wife and two young children, told a similar story.
"There's human waste all over the floor in some of the bathrooms and they're overflowing -- and in the state rooms," he said. "The elevators have not been working. They've been turning them on and off, on and off."
An announcement over the ship's public address system said they were trying to fix the problem and were working on the generators, according to Stark. A few hours later, another announcement was made, saying the problem was worse than expected.MORE
