I want to start by saying cruises are made by the people taking them not by getting mad/upset at every little problem. With that being said my family and I had a great time. I cruised with my wife, daughter (7yr old), and dad. My wife and daughter shared a cabin (she has already wrote a review cabin 6208) and my dad and I shared a room.
Embarkation- Couldn't have been easier. From the time we pulled into drop off our bags to getting on the ship was all of 30 mins. We did show up at about 1 PM so most of the crowd was already on board. But Carnival really has this down even when dealing a wheelchair like we had too.
Cabin- I was in 6212. It was the 3rd cabin from the front on the port side. Great cabin with a great balcony. Enough space for my dad and I. You can probably fit 3 people in nicely, but I wouldn't go past that. Take a bungee cord with you so you get keep the balcony door open. Our room steward was Jose and he rocked always there when we needed him and he was very polite. He never said no or wait which was nice. One little problem was we were at the front of the ship and our dining room (Scarlett) was in the back of the ship. This was a problem because the front elevators couldn't get you to the back dining on the 3rd floor. So we would have to go to the back of the ship on deck 6 wait forever for an elevator and go down to the 3rd floor.
