Cruise lines charge a "single supplement" to passengers traveling solo. Typically the cruise line starts with the per-person rate based on double occupancy and adds 50-100% to the price for a single. That means that a cabin that sells for $1,000 per person based on double occupancy would be sold to a single for $1,500 to $2,000.

From the cruise line's perspective, what they are selling is space on the ship. If there are two or more people in a cabin, they split the cost of that space. People traveling alone pay for all the space by themselves.
