You better be getting up early. Plans call for the world's largest cruise ship to appear at the entrance to the Port of Los Angeles around 4:45 a.m. on Wednesday. The Queen Mary 2 will then be towed—backwards—into the dock about 6 am. A public viewing area opens at 7 at Berth 87 next to the L.A. World Cruise Terminal. As we told you in December, the QM2 is too tall to pass under the Vincent Thomas Bridge and too long to turn once inside the port. The ship apparently leaves tomorrow evening for a three-day cruise to Ensenada, but will slide back into the outer harbor around noon Thursday under Coast Guard escort to salute the original Queen Mary at its berth in the Port of Long Beach. The QM2 will be around off and on through March 8, when it sails for New York.
