Each bar has pluses and negatives depending on your point of reference.
For a quiet, very small bar, we loved Half Moon. Only 5-6 seats at the bar, but there are a number of tables for 2 down the hallway next to windows. These tables for 2 are across from the exclusive CO dining room heading aft. We liked Half Moon when we wanted to stay for some time and just enjoy talking between ourselves/other bar seat mates and talking to the bartender. This was our go to pre dinner drink and post dinner/entertainment nightcap. They make some interesting drinks.
Bilboard bar is neat as it is in the entertainment area and thus you get to hear the music when they are playing. Lots of seating and I think about 8 seats at the bar itself. On our sailing, they had a number of bartenders and due to the larger crowd, were busy when we were there, thus we tended to choose a table for 2/4 and have a wait staff person take our order. This was our bar for show drinks.
Never sat at Ocean bar, but did walk pass it. The bar seating seemed to be full most of the time with some people standing next to the bar seats.
Taramind has a very small bar. Bartender was customer centric and gave us some guidance to trying something we had not tried before and we did enjoy the restaurant once and you are looking aft
Enjoy your cruise and let us know your favorite bar area.
We loved the entertainment area with great music every night, either Rock and Roll, Blues, or two pianos with themed music or requests. We have booked Rotterdam again.
