Also, row 12 ain’t bad at all imho.
Yes- next to the lavs, but the placement of the curtain (between 12/lav), and the fact that most foot traffic to the lavs is typically from the seats behind the galley - so, stays behind the curtain makes it a non issue for me.
Traveling as a family of 4, 11/12 G/K are our preferred seats and the block makes it a lot easier to get these seats nowadays (I’m DM, never had an issue getting them to open for the rest of the family who are not).
