Hi, looking to book my seats for the summer holidays, out Heathrow to Washington DC and back Barbados to Gatwick. Plane is a330. We want 4 seats in UC, all adults. It would be nice to sit opposite each other but I've heard bad things about the length of the middle seats when in bed mode. My daughter and I would be in these seats, I'm 5ft1 and she's 5ft4. Would I be correct in presuming that because we're short arses the reduced seat length wouldn't be a problem or are they REALLY short. Thanks.
I've done it numerous times with 4 of us and although we are all tall and slim I couldn't imagine sitting in the middle section which is 5 inches shorter even if I were more vertically challenged.

You won't 'see' much of each other sitting side by side, and actually the configuration (for me) lends itself better for you to be all in a line and you can hang your head over the partition. You certainly can't chat easily across the aisle.
