We were in 11746 on Iona in July and it is still a problem. I didn't know about these forums at the time of booking and only stumbled across them a few days before departure so was too late to change the cabin (unless I wanted to pay the extortionate upgrade fee!). It was fine when the ship was docked, but when moving and especially on Sun & Fri which were sea days and the pools were busy even though the weather was poor, it did make the balcony unusable.
