Are you really telling us all (most of us older than you with children and grandchildren), that you have never been in a restaurant, movie, cruiseship or especially AIRPLANE where children haven’t driven you nuts?
I am really telling you YES. I have no idea how old you are but I will be 50 soon. Never ever been driven nuts by a child in a restaurant, movie, cruiseship or AIRPLANE. I have been annoyed by rude, drunk and unruly adults on numerous occassions but I refuse to let them drive me nuts or ruin my evening.
I’ve taught high school for 31 years, I have patience, but when you spend $3K on a cruise vacation or $2500 to fly to Europe, the last thing you want to be is trapped with a screaming kid or small kids that the parents don’t control.
So basically you’re saying people with kids can’t travel overseas unless they rent their own small private plane–so as to spare you the risk of being driven nuts. The person with kids is spending the same money per seat as you are to fly overseas.
There are many establishments that children are not allowed to enter - especially those serving alcohol. What is wrong with hiring a babysitter for an evening for your child under the age of 6?
Nothing, but If my children know how to behave and do behave why can’t they come out for a nice diner with their parents? We have often done that after the ballet (yes we take them to the ballet and I know its hard to believe but they manage to sit still and be quiet) with no issues. Why should I be relegated to some place like Red Robin or some pizza joint?
Obviously at a place like DisneyWorld,
Given the space and range of activities available on a cruise ship how is a cruise ship so different from DisneyWorld?
I would expect children of all ages to be admitted everywhere, however, if I’m going to spend $200 on a nice dinner at Ruth Chriss, I don’t want to sit next to a screaming 13 month old with poopy diapers!

Yes because thats all 13 month old children do. I find they spend more time sleeping and playing quietly than they do screaming. Just last month we were at a very nice restaurant and at the table next to us was a baby of roughly the age you cite–slept the whole time they were there–not a peep, no screaming, no poopy diapers. Imagine the nerve of that child! I should have told those parents they better wake that child up and make it scream–don’t want to disappoint people.
Oh and I don’t want to sit next to some cranky old person who complains about how their steak is cooked, how long it’s taking, that the service isn’t good enough, theirs not enough vodka in this martini or next to some self-important adult who can’t stop talking on their smart phone.
