CHERRY HILLS VILLAGE - Jessica Sager's last contact with her sister Shirley Karr came Monday through a broken cell-phone signal on board a crippled Carnival Cruise ship in the Gulf of Mexico.

Karr requested one thing: someone should make sure her tickets to Thursday's Carrie Underwood concert in Broomfield don't go to waste.

"I spent Monday trying to figure out Carrie Underwood tickets for her daughter," Sager said.

Karr, along with her husband, are from Lakewood. They are two of more than 4,000 people on-board the Carnival Triumph cruise ship that experienced an engine fire Sunday morning.

Tug boats are now pulling the 900-foot, 100,000 ton ship to Mobile, Ala. The ship is expected in port Thursday afternoon.

Karr received the cruise from her employer. She probably never thought her free vacation would cost so much in the way of inconvenience.

"There's a three hour wait just to get any food," Sager said. "When she got food it was a piece of bread and a slice of a tomato and some dry Rice Krispies."

Carnival Cruise Lines has apologized and has offered refunds to passengers of this cruise, along with other cruises on the same ship through April.

"We are obviously very, very sorry about what is taking place," Carnival Cruise Lines President and CEO Gerry Cahill said. "There is no question that conditions on board the ship are very challenging."

Another Carnival ship delivered food Tuesday, but there is little running water, and less than a dozen working toilets, according to reports.

"On Monday she said it was pretty bad. She said there's a bunch of sewage on the lower levels," Sagar said. "They are using bags for bathrooms and showers for bathrooms."

Sager hopes her sister can find a way home safely and quickly.

"My biggest concern for her is she can't get off this boat," she said.

When she does get off the boat, she'll have to find another Carrie Underwood concert to attend. It won't be on Feb. 14.

"It's Valentine's Day tomorrow, and they'll be celebrating Valentine's Day on the never ending boat ride," she said.
