I usually enjoy watching movies on the lido deck during cruises, and most passengers tend to be respectful and quiet, which makes for a good experience.
However, on my current cruise, a couple was allowing their two children to run around, scream, and play on the chairs directly behind us during the movie. It became very distracting and made it hard to enjoy the screening.
I am not against families bringing children to the movie area, but I wish there was more consideration so that others can actually watch and enjoy it peacefully.
