Cruising alone can be an incredible experience. You get to explore new destinations, enjoy onboard entertainment, and travel on your own schedule without worrying about anyone else’s itinerary. Unfortunately, many solo travelers quickly discover an unexpected expense known as the single supplement fee. Because most cruise cabins are priced assuming two passengers share the room, cruise lines often charge solo guests an extra fee that can raise the total cost dramatically. In many cases, solo travelers may pay anywhere from 125% to 200% of the standard fare just to sail alone. If you’re planning a cruise as a solo traveler, these strategies can save you hundreds or even thousands of dollars.
