I took a Christmas cruise on the Poesia with MSC for Christmas. Before that cruise I read up on the cruise line and ship and as MSC is new to the Caribbean and I got a lot of value out of the other reviews I thought I would share.
Pre-Criuse:
My in laws got 3 rooms on the Poisa for the Christmas cruise December 20-27th. We got one inside room for my wife and I, one balcony for my in laws and a "single" for my brother in law. They do allow one person to occupy a room, which is the same as the 2 person room, and pay 50% of the second ticket, paying 150% of the single person price.
I have never had a balcony before, but our room was very nice and large, I feel like it was laid our better than any other ship we have been on. When we arrived we did find a few problems though: our beds were arranged as singles, our safe was locked in the open position and our shower leaked. Once we found our room steward which wasn't easy we had then fix the beds at dinner (they had to get king sheets). Our steward found an engineer to fix our safe and also called someone about our shower leaking into the room. It wasn't that the wet floor spilled out it was coming from the wall where the drain was. They sent 2 groups of people to look at our drain and snaked it, but it leaked for the whole cruise. The room stewards are more like the cleaning people at a decent hotel than any other cruise I have been on. They do a good job cleaning the room, but don't do anything else and when you rarely see them in the hall then don't acknowledge you like on other ships. This was all fine to me, but I think my wife secretly missed the towel animals.
