Any thoughts for a family of four in F to and from SIN? 77N on the way out and A380 on the way back. Two GCH, and two boys 12 & 9

I was thinking either a whole row, (2AEFK on the A380) and/or 1A 1E 2A 2E on the 777 (2K is occupied)

I've tried searching the thread, but no real help.......

all suggestions gratefully received!

Thanks
