Not a good start to the tourist season, but despite the damage looking bad, I would expect these to be rebuilt in a week or so. Unless insurance bureaucracy gets in the way.
Almost all the beachfront shops and restaurants you see are rebuilt each year, they’re are temporary structures that struggle to survive the winter storms anyhow.
And as another positive note, Plakias is well know for being a very peaceful, relaxing and isolated resort, so could probably do with a little excitement. Feel sorry for the business owners though ..
