Lots of the people answering are couples though. It is quite different on your own
I dream of moving to the seaside every time I go there but my practical side knows better so I shall wave bye bye to that idea. It's cold and lonely in the winter and full of old people. God's waiting room 
I shall move eventually. I will be on my own but don't yet know where to.
The winter is the best bit, walking the beach on Christmas Day is bliss. As for being full of old people, there don't seem to be many more than anywhere else I go. We do have plenty of craft groups, classes, U3A etc, things for retired folk to join, but then I don't know what other towns offer. Ditto good public transport. And the weather on the South Coast is very good too.
