There is no one-size-fits-all cruise ideal for everyone, but <a href="http://travel.usnews.com" target="_hplink">U.S. News</a>' <a href="http://travel.usnews.com/cruises/" target="_hplink">Best Cruises 2015</a> rankings make the decision-making process easier by identifying the lines that consistently deliver exceptional experiences. This year, we evaluated 15 cruise lines in five categories, taking into account key factors, such as health evaluations, traveler approval and reputation among critics, to determine the best cruise lines of 2015. For our second annual rankings, there have been some shake-ups. While some industry heavyweights reclaimed the "Best Cruise Line" crown in their respective categories for the second-year running, a few newcomers climbed the ranks. Before you book your cruise, explore the lines that came out on top.
