The last LGW-MCO flight I flew on they used both galleys (although they were a rather disorganised - new to long haul - crew, so that may have made a difference...). I believe that Club Kitchen was located at the Door 1 galley.

Personally I would avoid the second, smaller CW cabin... Have only sat in it once, but we had problems with "traffic" from WT+/WT- - i.e. people going through to use the club loos or to visit friends/family in club . This MAY have been more of a problem on our particular flight, BUT it is always going to be easier for crew to spot and stop economy passengers before they get to the furthest front CW cabin - keeping people out of the second CW cabin is always going to be harder...

Had 2JK last time and quite liked those (there are no row 1 window/aisle seat combinations). 2AB may be better - further from lavatories. Have done 4AB before and liked them (window seat with no-one to climb out over). 3DE iis another possibility - 3E is pretty private.

I think that the 3 class 777s are MUCH nicer than the 4 class ones... ^

(sulking because she can't choose seats for her next BA flight on a 3 Class 777 until T-24...)
