Holland America Line prides itself on its rich heritage. It has been taking Americans to exotic destinations around the world for more than one hundred forty years. That’s right. Holland America was founded in the latter half of the 19th century, when it was known as the Netherlands-America Steamship Company. Today its fleet consists of fifteen mid-size cruise ships that collectively offer over five hundred sailings in one year. It’s a relief that it gives out exclusive discounts to customers who book online using Holland America Promo Code.
