I was going to post a very detailed review as I did take notes, but I do not want to be here typing for an hour so I will condense it.
Day 1- Embarking
The sooner you arrive to the Port the lower boarding zone number you receive, I was zone 4 and we arrived at 10am and they allowed us on the ship around 12:30.
4171 balcony was clean and spacious lots of space for clothes, bathroom had just enough room.
