I can't stand the evasive answers anymore...
Slash, as a captain, you are practically no different from an FO when it comes to accommodation...you would be offered Meyday Heights (though this will be full soon)or Meydan South. Captains get a bit more allowance (cash) to find their own accommodation, if they wish, than FO's.
We're not doing DEC's on the 380. It will happen, but not yet, I believe.
As suggested: do the reading before asking lots of questions - there are lots of answers around here already.
