My wife surely wouldn’t. The upper deck lav leaked on our heads for half the flight from Sydney to LA. What’s worse than a 16 hour flight? A 16 hour flight where you have to stand in the aisles.
(FWIW, I think the A380 has superb pax comfort.)
I'm pretty sure we dropped about 500 feet straight down, but all I remember was being amazed how my cup of pepsi stayed on my tray and didn't fall over.
