To see cruises that offer low single supplements, use the Find a Bargain box on the left.
Cruise lines generally charge a "single supplement" to passengers traveling solo. From the cruise line's perspective, what they are selling is cabin space, and 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.
Most cruise lines start with the per-person rate based on double occupancy and add 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.
At Vacations To Go, we're sympathetic to our single customers' desires for a great price. We've scoured tens of thousands of departures to identify the lowest single supplements for our customers. In some cases, there's no single supplement at all.
