We chose a balcony room on the basis that we had 3 adults this time (my wife and I plus my 80 year old mother) and could not easily arrange for a fourth person and did not want a room with a drop down bunk -- some of these balcony rooms have a couch that can be made into a bed. I would highly recommend this solution if you have 3 folks and don't want to use a drop down bunk. The only problem was that I think our room steward was lazy and did not ever make the couch/bed into just a couch during the day. My 80 year old mother used the couch/bed and said it was fine.
Embarkation:
This went fairly smoothly as we did arrive around 2:00 p.m. that afternoon.
Had a balcony room with a couch/bed which was really helpful to take my 80 year old mother on her first cruise with me and my wife. As it was just below the mermail buffet/grill, it was also great for going to the buffet or the main deck activities.
