We choose the cruise because of the itinerary - United Arab Emirates plus Qatar, Bahrain and Oman.
To be fair the ship - Mein Schiff 4 - is beautiful. The staterooms are well appointed, the dining - no matter which restaurant you choose is not to be faulted and the all inclusive concept very nice. With the exception of the wines served in the all incl. restaurants that are not of good quality. But you can circumnavigate that by ordering your much better wine at the all incl. bars and then just take them with you to your restaurant table.
As long as you don't go during school vacation time when kids are running riot all over the ship at all hours - as we experienced during a Mein Schiff cruise in January 2018, it is quite pleasant. During sea days it is heard to find a sun lounger as all are reserved and the crew doesn't bother to free the loungers even if there is nobody there half the time. Very German (and I am one myself).
