It really depends on the balconies. On some balconies you can be seen from above. Others can be seen from people farther down the side of the ship. You always have to contend with the rubber neck neighbor who may stick their head around the side of the partition.
Often the aft wraparound balconies are the most private except the ones that can be seen from above.

You are also behind a glass partition and may not have full sun depending on the location of the balcony and the direction the ship is heading.

You need to be aware of not only passing ships but those darn sneaky submarines--with the powerful periscopes they have, they can zero in on the rivets of a ship so they could zero in on those--- well someone on the balcony !!
Now if we can only find out which ship, stateroom number and date of sailing op is referring to. Cabins around yours may end up selling out!!
2008-Valor and Glory
2009-Spirit and Splendor
2010-Freedom of the Seas and Mariner of the Seas
2012-Allure of the Seas and Navigator of the Seas
Also there can be reflections, so you can see into your neighbors balcony, therefore, he can see into yours..however, you can also hear when your neighbors are out on the balcony, so knowing when they are there or not may make a difference in the level of privacy. DH and I have only been on 2 cruises, both times we spent most of our time on our balcony..very rarely did we see or hear neighbors.....enjoy your cruise!
One of the best photos I have re / cruising is of a neighbor ( don't know who she was ) in a silhouette through the glass of the balcony. I was sitting on our balcony one morning watching the sun come up. She came out and the sun was perfectly silhouetting her through the partition between our balconies.She was wearing a " shortie " nighty. She apparently yawned and stretched and with the sun outlining her, the colors, etc. it made for a perfect photo--nothing naughty, nothing nude, just a lady's silhouette in a big stretch with her arms extended up and her head slightly tilted back-- with the sun and colors behind her. I couldn't have had her pose any better than what she did--just one of those times when the camera was handy, everything was perfectly in place and I was lucky enough to get the shot. I think on every cruise there's always that one photo you like better than the rest and this one is one of my all time favorites.
Thanks, who ever you were!!
