We just got off this ship yesterday - we really enjoyed the BB King band! It was pretty popular every night and lots of people got up to dance (depending on song selection). They were often at 8 / 9 / 10 with 45 min sets. The whole band was pretty talented and we saw a lot of their performances.
We walked through the Billboard and Rolling Stones bands, but neither sounded great in our opinion. That said, seemed like a lot of people in those venues.
In the World Stage, it was usually 7:30 / 9:30 performances. First night was the documentary as mentioned above, 2 nights of the Step Up dancers, 1 comedian, 1 saxophonist, and 1 night combined (comedy / saxophonist). There might have been one night I forgot.
There were a few nights with movies on Lido, one night was Barbie but I don’t recall the others.
Overall we enjoyed the evening entertainment and it was a good variety.
