I'm terribly British about these things and don't usually pipe up, but the OP is absolutely right to be frustrated in my opinion.
There should be enough capacity in the CCR to seat many more diners
There should be more cabanas
There should be more shower suites, and these should always be maintained
on a rolling basis (so no more than one or two are ever out of use)
CCR loos should be cleaned more frequently, and there should be more of them
There should be more capacity for last minute massage / treatment appointments too.
The only point on which I can't see any improvement is seating on board. Once those seats are taken by others, that's it.
The shower situation over the summer has been diabolical, and continues to be. The wait for a table in the CCR is just not acceptable. I am turned away far too often, and on the occasions I do manage to get a table near the front on either side I hear FAR too many other people being turned away.
(I don't bother with the BA treatments personally as they are not a patch on what QF or AF offer in F)
Don't get me started on the Cabanas. I have 3 F flights from LHR to LAX over the next 2 months and in NO case is Quintessentially Useless able to reserve a Cabana for me in EITHER direction during my layovers from TLS.
