If you are keen on having some shade and privacy on the balcony, I would suggest seeing if there is an opportunity to change to one of the superior deluxe balconies at the aft of E deck. These cabins and balconies are exactly the same size and layout as those on D deck but have a covered balcony.
We love the E deck cabins. The E deck cabins are above an entertainment venue - but we have never been bothered by noise when staying on E deck starboard side. I understand the speakers in the club are on the port side - so that might be something to be wary of if you are able to change to E deck.
