I just returned from the 26 February Eastern Carib cruise. I found the ship, food & service to be on par with what I've had on HAL & Cunard and above that of RCCL & NCL(DAWN 12/30/04 cruise).
The entertainment was Continental to appeal to the various nationalities onboard - as far as "latin "music - yes some was mixed in but hardly that is all that was on offer. It may be strange to hear a Croation band sing American Standards but in the Cotton Club each evening it happened & the dance floor was packed. In the piano bar the Italian pianist had an Italian accent......in Byblos(disco) the Euro mix was better than hearing rap all nite - all ages were up dancing on the Opera(not so on NCL Dawn)
After about 50 cruises on various lines...I found the Opera refreshing.
