Hello newtocruising, I had a balcony sateroom the the Victory in April - An exact sister ship to the Triumph, it was really nice. Our room was on Veranda Deck, at the back of the ship. It had 2 twin beds, pushed together as a king, and a single convertable sofa. There was only two of us in the room, so we did not need the sofa. Having the balcony was great.
Be vary careful of opening the balcony door when the airconditioning is on high. it will cause condensation to form all over the room, and the smoke detector may be fooled into going off. This happened 3 times to us on the Victory, and each time an officer on the bridge phoned the room to make sure all was ok - after the 3rd time, a technician serviced the unit.
If you are going to have 4 people in the room, you will need to get a room with an upper berth that folds into the wall.
If you go to carnival's website, look at the deck plans and find a room with a litte infinity sign - they have a queen sized bed, a single convertable sofa and an upper berth.
