I am not sure the increased leg room is worth it in row 33. IME, people gather there in front of your seat the entire flight waiting to use the lavatories. Then you have to listen to them, the toilets flushing and have them tripping over your legs. People are fond of walking their babies up and down the aisles and then letting them play in this area. It's just so cute when they grab your legs, or when teenagers in line for the lavs have fun opening the shade to see if it's still sunny outside which flashes light into your eyes.
Just take this into consideration. It was not a pleasant 11 hours.
