This was our second time on the Poesia and we found the ship in the same condition which is a good thing as two years has passed. It does take away from the wow factor to get back on the same ship as there isn't that 'day of discovery' as you explore around deck by deck.
Overall our experience was good and what we were expecting. I had booked a balcony for the price of an inside (in an e-mailed special I'd received from MSC almost a year in advance) which made it a fantastic price. This is one of the reasons we cruise with MSC as they are the least expensive cruise for the dates we need. Plus their beer and wine packages make the final bill more palatable than on other lines.
Embarkation involved a wait of about 20 minutes but it was very orderly and there were lots of seats so it was not a problem. We were on board by 12h15. Our cabin was almost ready and we were encouraged to stow our luggage in the closet and go have lunch.
