I was leery of going on a cruise that my brother-in-law booked on MSC Poesia because of all the bad reviews on the internet. We found it wasn't too bad after all.
Embarkation at Port Everglades was fine and very quick but that was probably because the ship already was part full with folks on two week cruises.
Two days at sea were great but don't look for lots of organization of events, entertainment and activities as on NCL or others. The majority of folks on this cruise were over 65. Entertainment was not so good but theatre shows in the eventing were OK.
