Everyone hates the seats in the -300 rest area, but the bunks are superb. And yeah that lav is the best I've ever seen in an airplane.

Hint on the dumb waiter - never, ever try to bring the tray straight up out of the waiter... it doesn't fit and you will spill salad and vinagerette down into the unit, where it will then drip out into the aisle.

Instead, there's a latch on the side that opens to release the tray laterally. They need a training session for this!
