My first ever cruise was on Carnival (2000). (Thought I’d never cruise again! Forward to 2011, MSC, cruise bug bit). I don’t recollect piano bar entertainment. My abiding memory was a Beatles tribute in one of the lounges; absolutely loved it, but it was sooo short.
Same on NCL (in “The Cave” - you really had to get there way before the show to get a seat - way too small a venue for such a popular event ). Why can’t cruise lines see that a Beatles tribute is still a huge draw?? I know that MSC does a ‘tribute’ in the theatre, but a whole night in one of the lounges would be a real treat.
Having said that, I wish that entertainers onboard wouldn’t make their own arrangements when doing Beatles ‘tributes’ (thinking of our experience on Seashore in the Med).
