The staff should police the chair situation, passengers can't. I have no problem with anyone who wants to get up early to reserve a chair as long as they use the bloody thing! I can't be bothered, I like a leisurely start to the day! I cannot understand anyone who thinks it is ok to reserve a chair & NOT use it. We seldom use the chairs & have never used a pool on a ship (well once, years ago) as it is usually impossible to get one, on our last cruise we spent a couple of hours on a sunbed once out of a month on board, never got NEAR a pool or jacuzzi.
