As this was not our first cruise we had some reservations about the Carnival Spirit, however these were soon overcome.
Embarkation - easy and quick, we had a12:00 boarding and were at the OPT about 11:30, dropped our bags off, and thought we would just see what was happening with boarding, no problems, joined a very short queue and within 15 minutes we were walking onto the ship, customs done, sign&sail cards in our hands. Plenty of staff in red shirts with "ask me" welcoming us aboard and directing us to the lido deck for lunch. We had the buffet with friends and were in our cabin about 1pm.
Cabin 7200 - extended balcony - great room, good location, not too far from the elevators which take you to the buffet and pool areas. The extended balcony was bigger than I was expecting, 2 chairs and a little table. We took a bungee cord to keep the door open as I like fresh air and the door is not a sliding one, however wwe just used the little table to keep the door open. This cabin has no rooms opposite so there is very little noise and passing traffic.
Good room location, close to elevators but little through traffic. No rooms opposite so you don't hear doors banging closed. Good storage. Extended balcony, just gives you a bit more space. Bathroom good, bigger showers than p&o and princess. I would recommend this room.
