Great thoughts. Most of the time, we have not had issues on X with kids. But we sure did on one cruise. We also sailed on Celebrity on a 'holiday' cruise in South America. X had advertised heavily in the SA market: they permitted 2 adults to pay 'full fare' and then they could bring as many kids that would fit in the cabin for $100 each. IT WAS A DISASTER, but nobody responded when many of us wrote letters after the cruise. I have never seen the 'pack' mentality of the kids that I saw on that cruise, and the Total lack of parenting. Kids running laps around the OVC (dodging adults on walkers and servers with heavy trays). Kids in the casino (doing cartwheels in the aisle) and sitting on their parents' laps while the parent was gambling. Kids in lounges at all hours -- yelling at full volume. Elevators out of service because packs of kids repeatedly smeared food (and worse) all over the walls. Kids congregating/sitting on the stairs, making it impossible to pass by. I could go on, but suffice it to say it was awful. For what it's worth, this was a 16-or so night cruise, starting on Dec 24, so most families from the United States don't have that much vacation time off immediately after Christmas. And the four times I tried to talk to parents when their kid was doing something Very dangerous, they pretended they didn't speak English. When we asked some of the managers for assistance, they couldn't help. Several crew members told us this happened every holiday cruise in South America.
