Why are we always disappointed by CLs?

Over the years we have tried perhaps a dozen or so CLs, and have almost always found them disappointing.  The one where the chemical emptying point was "over there" (never found it); the one which charged £20 a night on account of having facilities - facilities that were in fact shared with an encampment of twice as many vans that were not on the CL and apparently used by workmen; the ones made uncomfortable by a number of other, often tatty, vans scattered around.  Where are we going wrong?
