Sorry, you do not state whether you are male or female.
It is not uncommon for both to go to Corfu on their own, because as they have all said, as do most, you will always meet up with others either on their own or in groups or families. That is the fun thing about Corfu, both locals and holidaymakers being so friendly. It is all part of being on Corfu.
As for females, those who have travelled alone to Corfu find it very very safe to do so, and consider going back again.
Hope this helps until someone who has comes on site.
