Six Star Cruises is a luxury cruise agency that is part of the Cruise118 family, which itself is a subsidiary of the World Travel Holdings (WTH) group. In 2026, WTH remains one of the world's largest cruise agencies and travel distributors, owning a vast portfolio of brands including Cruises.com and CheapCruises.com. Six Star Cruises specifically targets the ultra-luxury segment of the market, specializing in "all-inclusive" high-end voyages with lines like Regent Seven Seas, Silversea, and Seabourn. While the parent company is based in the United States (headquartered in Wilmington, MA), the Six Star Cruises brand operates heavily within the UK market out of its offices in Lancashire. This ownership structure allows them to provide highly specialized, concierge-level service backed by the massive scale and technological infrastructure of a global travel conglomerate.
