I'm relatively introverted so I like to be alone. But having my daughter so young I'm rarely if ever alone. And I've never lived entirely alone in my whole life. I always had at least a roommate. Even in the time periods when it was just me and my kiddo I had a roommate, so I do actually forget what it's like to do things alone.
I absolutely love going to movies alone. I also like eating alone. But I love to people watch so it's always entertaining to me no matter what. Also like CW said sitting at the bar is a very different eat alone experience. If there's a counter to eat at, even if there's no bar, I like to sit there. I was a waitress and bartender in my youth and there's nothing I love more than a slightly annoyed server who will tell you everything about the restaurant, the staff, and the entire area if you give them the chance.
A little town by the sea sounds lovely, but if locals are telling you outright you won't want a house it's probably a safe bet that they are right. I hope you gets some clarity on all this housing stuff. Still wishing you lots of luck.
