Well, you can't complain at that offering from BA, plus the LCY. They got a bit of stick for pulling off LGW, but the above is not bad at all!
I suspect a fair amount of creative parking may be required, or more tugs to remote park a/c once they have disembarked their loads.
There are some stands where you can - or could - 'double park' but that was mainly for smaller types. Stand 1 used to be sliced up A/B/C when the need arose (mainly in the days of City Star).
