8139 is a great queit spot aft of the boat. It seems to be a little larger cabin with a nice size balcony (Verandah)/ Fantastic closet space and good bathroom. Close to the Lido aft deck and Lido Buffet restaurant, being aft it might be a little to far for people that can't walk far to get to the main restaurant, office, theater, shops, casinoetc. as they are forward down in the ship. There is no outside noise and we actually like the slight hum/noise of the AC as "white noise" drowning out any outside noise.
