59E and 59F
We finally got a chance to put my theory into practice earlier this week: with nothing better on the UD (and, frankly, slim pickings for anywhere), we plonked ourselves into 59EF. It worked a treat, and would have been perfect if 58E hadn't been a child whose legs simply weren't quite long enough to step over me without brushing against my legs - but given that I don't always manage it perfectly myself, I could forgive that.
Oh, and the power socket's circuit kept tripping out in the 59DEF unit, so the privacy divider kept dropping at random until we just left it down.
The cabin crew were brilliant about the meal service: as we each only wanted a starter and no main, they hand-ran two trays down to us as soon as they had taken all the orders, so we were finished, cleared away and in bed about 45 minutes after take-off. ^
