The simple fact is that we can't get past entrenched inter service views with this one.
It would appear that if you are in the RAF then temporary accomodation isn't good enough to afford crew rest (which we all know should be protected to the utmost extent possible) and is in some cases only going to cost more than hotels anyway.
If you aren't then you can't see how a modern system could be insufficiently comfortable and suspect hotels would be more expensive in the long run. You would also like to know what the pan-service plan is for KAF 2 (the revenge) when there is no festering hotel!
So until someone figures out how much we'd save or otherwise we don't really have a debate, just a slanging match.
Oh and incidentally - for you crew rest enthusiasts out there. I know what the evidence says and I know what the rules say. However, 1 Gp crew rest ASOs for CVS operations were different to shore based....so you ended up asking yourself the question 'Why?' as if it was safe 'embarked' why wasn't it safe 'ashore'?
