You are absolutely right about the Choir of Man! We booked it twice, on your advice, and were very glad that we did. We attended one of the comedian shows in the theatre, and it was pretty good. I think I would have liked to see more of the events in the Atrium, but you have to be so early to get a seat.
Starting in Jan 2024, they've also introduced a new $20USD per day fee. I think they said it was gratuity for those not included in the staff that get the other gratuity. We called it the "being on the boat fee." I just wish that they would build all of the fees into the cost of the cruise upfront. It makes going on a cruise feel like buying a car. The sticker price is not what you pay in the end.
