I was just on the Grand and the Promanade deck does not go by any balconies. Emerald is deck 8 and the Promanade is deck 7 for most of it although you do go up some stairs towards the Bow. The balconies on the Emerald deck are completely covered, at least ours was. I think the balconies on the Dolphin deck are also covered. It's after that that you have the tiered balconies.
