I also used the empty 18A behind me as my "office" and dining room. To be honest, I don't know why people hate angled seats so much. They were just as nice as the straight seats. (minus the good window views) Of course, for sleeping, the straight seats were more private and cozier.

9A/9L were terrible because people seem to hang around there even when the lavs were not occupied. Not to mention the lav door in front of 9A was like a big swing door and people frequently made loud noises closing it.
