The doors leading to balconies are on the Upper Deck cabins, Pauline. The Main Deck cabins we are speaking of do not have any doors except the solid door which leads to the inside hallway.
Besides that solid door, they have two portholes which you cannot see out of unless you are over six feet tall. That may not be a problem for some, but it is for others.
My point is that, in spite of my very specific questions about these two cabins, the reservations agent gave me incorrect information, and that mistake impacted the quality of our trip. Someone needs to address that issue, and to make sure that in the future the reservations agents have the correct data on each cabin on the ship.
