I don’t have real claustrophobia, but I like fresh air and I love the sound of the ocean. For those two reasons we almost always get at least a balcony room. Yes we can see and hear the ocean from many areas on the ship, but rarely are they as quiet as our balcony.
You my find that you’ll spend mornings enjoying your coffee out there, or an afternoon break from all the noise and activity to just relax and take a quick nap, or have a glass of wine before going to dinner and the evening activities.
