"Are we bringing this virus off the ship with us?" asked Shannon Blace, a passenger from Toronto who was traveling with a party of 12 people -- 10 of whom have been sick. "We're all going to hotels all over the New York area. Will we be spreading the virus to the Super Bowl this weekend?"
Blace told CNN via telephone that she was upset and felt as if she had spent a week on a floating prison.
"It's just been a big nightmare," she said. "It feels like (Royal Caribbean) never had a contingency plan in place to handle an epidemic on the ship."
Blace said it was evident early on that many people were sick. She felt the ship should have been turned around.
"On Wednesday night, I was in the dining room and a woman was vomiting into her napkin," she said. "There were people walking around in their pajamas with vomit and diarrhea on them. People were barfing all over the place."
Not all passengers, however, were dissatisfied.
"We had a wonderful cruise, and they were very nice," said Margery Feinstein
On Sunday, five stool samples were sent from the ship to the CDC in Atlanta, where the samples were expected to arrive the next day, CDC sources told CNN. But the arrival of the samples has been delayed because of paperwork issues and the bad weather in the Southeast.
