Thanks all for the replies and suggestions.

I can see the seat map in my Emirates booking. Basically all bassinet options are still available and I was just wondering are there any particular locations on the plane that are better than others.

I think we will go for row 45 on the one segment. Still tempted to go for the two seat config on the upper deck on the segment where this is available. Would people really think we are selfish? I have flown upper deck economy before and there were two babies- never crossed my mind that they were selfish.
