Your far enough away from the lifts that you will not get any noise from them, they are really very quiet actually. Besides if you look at the deck
plan it shows them in their own separated area so people tend to congregate in that foyer plus you are four cabins down the hall. Stairwells on these
grand class ships are always quiet except for an occasional gang of kids and that isn't the norm even if there are a lot of kids on your cruise.
The outside double /balcony are comfortable cabins for two, the Baja balconies are a little small but room enough for two sharing a glass of wine.
The only way to get a bigger balcony would be to go for the Caribe deck, the balconies are almost twice as big.
