The cruise line industry is a sort of microcosm within the travel sector focused on seafaring, usually highly luxurious voyages. Cruise stocks were hit hard by the Covid-19 pandemic but are starting to return to full capacity. There are very few pure-play cruise stocks available on U.S. exchanges. These include Lindblad Expeditions, Carnival, and Norwegian Cruise Line. Other entertainment companies like Walt Disney also run their fair share of cruises, however.
