Arrrggghhhh!
I just returned from a lovely week away in the Algarve.
I was not able to get a sun lounger by the pool during my entire stay! Every time I went to the pool, all of the sun loungers were reserved with towels/ books. There'd only be actual people on around half the loungers.
There were signs up everywhere asking people not to do this, yet every morning, without fail, a scrum of people would run out and do it anyway!
I'm not brave enough to tell anyone off or complain 
Has anyone been at a hotel that has actually put a stop to this twattery?
