I see. Thanks. Since the flight leave after 10pm, I'm hoping the kids would sleep most of it (so playing on the floor in row 7 is not that important). Which row is an exit row? Currently almost all E+ seats are available - ranging from 80 to 42 (non-recline ones).
Beside 7 and 21 - what are the best options? Why is row 12 cheaper than the rest?

Thanks
