Carnival Cruise Lines was hit with a second lawsuit relating to the ill-fated trip of the Triumph, filed in Miami federal court today by a Houston woman who according to her attorney suffered severe dehydration and bruising from aggressive food lines. Lisa Williams, 42, was so ill from the five days the ship was powerless at sea that she had to be given intravenous fluids in the emergency room when she returned home to Houston, her attorney, Spencer Aronfeld, told ABCNews.com.
