Crystal Cruises has been voted by readers of Travel + Leisure “The World’s Best Large-Ship Cruise Line” for the seventeenth consecutive year. The cruise line is the only luxury brand to win this award each year it has been issued. Service, destinations, activities, accommodations, food, and value are the six areas readers vote on to determine the award-winning company. “While we have delighted travelers this year with newly designed spaces, new services, and new value-conscious pricing, we have offered a consistency of experience that is unmatched in our industry," said Gregg Michel Crystal, president of Crystal Cruises. "Travel + Leisure's discerning readership clearly recognizes the best when they see it, and I couldn't be prouder of our staff for their generous service, creativity and attention to detail." Crystal Cruises has spent more than $100 million on upgrading its fleet of luxury cruise ships over the past five years.
