Oasis of the Seas, larger than life on the ocean's horizon Friday morning, swaggered into Port Everglades, sounding her horn as a crowd of onlookers at John U. Lloyd State Park beach let out a cheer. ``Wow!'' cried one early riser, joining revelers with binoculars and blankets to greet the 225,000-ton megaship. `It's so amazing!'' shrieked another. ``It's huge.'' The world's largest cruise ship was accompanied by a flotilla of small boats and doused by water cannons as she headed into her new home port.
