There are a few true balconies on the E class ships. Some are all the way in the rear, the sunset veranda’s, and there are also what they call porthole verandahs which are really very large windows, not small portholes and there are suites with real balconies, too.
this is a porthole verandah.. it has sliding glass doors and black out curtains, and you can go sit outside on the veranda without it, affecting the air conditioning in the stateroom
