that is really a hard question to answer,the entertainment varies from different lounges on the ship and the entertainers are contracted for a certain period of time. If someone tells you that so and so were playing the week they sailed and they were awesome, you could be dissapointed to find that they aren't there when you sail. It also depends upon your personal preference in music styles and what you think is good. As a general rule, the better dance/show type bands will be in the larger show lounge(Explorer's Lounge?).
