The original cruise salt room. NCL's Breakaway and Prima-class ships built the template every other line has since followed.
Access: Never included in fare. Full-cruise Thermal Suite pass or single/multi-day passes purchased separately, typically $99–$250 depending on ship, sailing length, and how early you book.
NCL's circuit is the most elaborate in this directory — on Prima-class ships you move through eight distinct thermal spaces. Built for a full afternoon, not a quick visit.
