There's a bit of a difference between beds you pay for on the beach and beds you don't pay for at a pool, isn't there? Free sunbeds are a courtesy, and I'm with Carl on this one. Tying up a sunbed when they're in short supply and not using it for hours is simply rude and thoughtless. We usually grab a free sunbed at Mistral or Waves, but we always eat or drink there, because that's the deal. If I'm not on the sunbed or in the sea or walking along the beach I'm having a Mythos in Mistral. At places like Nafsika I reckon residents have prior rights to the beds by the pool. Common sense and manners is all it takes.
