Another European cruise I undertook solo as part of a larger goal of seeing most of the continent. In particular, I chose this cruise b/c of Istanbul. I highly recommend trying to make it out to Istanbul is possible! It's an amazing city in many ways and I could easily spend a week there.
I had read many negative reviews about MSC. Personally, I think people need to chill out a bit. The Magnifica is a brand new ship - spotless. The service is excellent. The main differences are that:
1. Vast majority Europeans on board - which I think is great.
