Re: 11L (I swore I'd never post a where-to-sit message, but here I am... )

I'm flying solo LAX-NRT and back. For the return flight, I booked 11L in the second cabin, but the plane has since been switched to a 787-10 so 11L is back by the exit/galleys. I know there's an exit behind, and my concern is noise/light from the galleys. But I've also read reports from people who really like this seat. Should I stay put in 11L or move to one of the D/F "couple's seats" and put up the divider? Those who have sat here, is noise/light from the galley excessive or does the exit provide a barrier?

My priorities are isolation (I like the odd seats for that private-cabin feeling) and relative quiet for sleep.

Thx in advance!
