As a single person, if you are having second thoughts about going on a cruise, then the only advice for you is don’t hesitate and just go, be it small ships, big ships, luxury cruises or adventure cruises.
As a solo traveler on a cruise, you certainly have numerous alternatives for a cruising holiday. You can take a single's cruise vacation without having to pay any additional single surcharges.
There are many cruise liners that charge anything between 25 to 100% extra if you have a cabin to yourself. Yet there are a few cruise companies that have small cabins for single occupancy or may even allow single occupancy for the double cabins, if the cruise is not fully booked. Alternatively, most cruise liners will be able to find you a roommate of your sex, age and compatibility. This way you can take advantage of the lower double occupancy price as most cabins are meant for double occupancy.
Another thing about a cruise is that you do not have to eat alone if you do not want to. So, chances are that you will definitely find yourself a place on a table meant for eight.
Some people are usually under the misconception that they will get bored if they travel alone. Rest assured this would not happen; there are more activities and possibilities offered on a cruise than you will ever have time for. In fact, there are some tour operators that try to add the possibility of a romantic element by providing you the opportunity to look for partners—not just for the cruise but for life.
