The Carnival Splendor was 200 miles south of San Diego when an engine room fire cut its power early Monday, stranding the 3,299 passengers and 1,167 crew members on board. The 952-foot ship had no air conditioning, hot water or telephone service. Auxiliary power allowed toilets and cold running water to be restored Monday night.

The Mexican Riviera-bound ship, which was drifting about 55 miles off the northern Baja California coast, was in contact with the U.S. Coast Guard, which deployed aircraft and ships along with the U.S. Navy and Mexican Navy.Two Mexican seagoing tugboats contracted out of the port of Ensenada were expected to reach the cruise ship at middayTuesday and arrive back at the port around 8 p.m. PST Wednesday, Coast Guard Petty Officer Kevin Metcalf said.

Passengers will be taken by bus to California, said Joyce Oliva, a Carnival spokeswoman. She said she was unaware of any safety concerns from passengers or their families about traveling by bus in Mexico.

Ensenada is about 50 miles south of the nearest U.S. border crossing, in San Diego.

Once passengers are dropped off, the Splendor will be towed back to Long Beach, Calif., a journey that will take days. That's why the passengers will be dropped off in Mexico first.

"They didn't want to keep them aboard any longer than they had to," Metcalf said. "They're running only critical systems as of now."The U.S. Navy aircraft carrier USS Ronald Reagan, conducting maneuvers 120 miles south of San Diego, was diverted to help the ship. About 70,000 pounds of supplies, including bread, utensils, cups, milk, canned food and other items, will be flown to the 
Reagan, where helicopters will transfer them to the stricken cruise ship, Cmdr. Greg Hicks said.
