We literally just got back a couple days ago from a 7 day Eastern Med cruise on the Magnifica.
The long and short of it was we had a good time (because of the group of people we were with), the ship was nice, but the cruiseline leaves alot to be desired and we won't sail with them again.
We've been on 7 or 8 cruises, on lines like Carnival & Princess, and the ultra exclusive Sea Dream. We've done the Caribean, the Mediterranean, and the Baltic. So we have a bit of experience with cruising and European cruising.
