A man my DH works with has performed on a couple of cruises, not as a solo act but part of an ensemble with some solos. He plays saxophone I think. Anyway, he and his DW have fallen in love with cruising. They go a couple of times a year for him to perform.
Don't get me started on misbehaving kids and parents who ignore it. Why do they think they'll hurt their child's esteem by correcting them? Or is it, they think they paid for their cruise so their kids can do what they want? With so few children onboard you'd think you wouldn't have issues. As far as ipads and phones are concerned, there is no reason to have one out. There's really no need to record a show. It's disruptive to others and you miss so much when you are busy trying to record. The kids were probably bored with the show. When you take your family on a cruise, you need to sometimes sacrifice what you want for everyone's comfort. It's also a good time to teach manners.
