Just got off a Princess cruise with the ships theater show cast with 6 piece band, a piano bar singer, a string duo, a guitarist/singer, a 5 piece group with two singers, a female soloist. one of theses was always playing in thr reception/atrium area from noon on. There was always at least three venues to choose from from 5 PM on. Yes, I realize it was a much larger ship with twice the passengers.
There were 4 Trivia venues daily including progressive Trivia on sea days.
Always something to do !
When I was last on HAL, there was only one choice at a given hour. Has that changed ?
