It was a historic day (March 23) for global cruise brand Royal Caribbean International whose two Asian-based cruise ships Voyager of the Seas and Legend of the Seas both arrived at Marina Bay Cruise Centre Singapore in the morning and were berthed side by side for the first time here.  Voyager of the Seas, the largest cruise ship based in Asia, was starting on her 8-night cruise to Shanghai while her sister ship Legend of the Seas was leaving for a 2-night Malacca weekend cruise as part of her Singapore season.
