Two cruise ships with dozens of sick passengers on board have received a conditional approval to dock in south Florida. The two ill-fated cruise ships are awaiting word about when the vessels will be allowed to dock at Fort Lauderdale's Port Everglades after a conditional agreement was reached between officials in South Florida and Carnival Cruise Line. Broward County Commissioner Michael Udine tweeted that final terms would be released Thursday. Holland America Line said in an email that they're awaiting confirmation to disembark passengers and “get the nearly 1,200 well guests home immediately," as long as they are fit for travel in accordance with guidelines from the U.S. Centers for Disease Control. About 10 critically ill passengers would be taken to a hospital in Fort Lauderdale. Four passengers have died. Of the 1,250 passengers between the two ships, there are 311 Americans.
