I had in Benidorm an exclusive sensation: trying to reach the sea, I couldn't find how.
The reclining chairs were to tight that it really worked as a wall. I had to walk to a rocky area in the northern tip of Levante beach to find a passage, walking back in the water to the desired bathing area, with the wall of chairs allowing the occupants to have their feet in the water.
August in Benidorm is a nightmare!
A positive point - the way back was also so long, that I could dispense the towel.
