>>I guess you are entitled to your opinion. I believe it is the bigotry of low expectations at work.<<
It is the observations of low behavior. Your kids may be the exception but the reality is that well-behaved kids at adult venues are rare. Actually, well-parented kids are the rarity. As a frequent traveler, I thank you on behalf of your fellow travelers and diners for your well-behaved kids.
But there is no way to screen for that so the only fair thing is to have adult-only zones. Just as there are family resorts and adult-only resorts in other countries and SHOULD be here.
I think perhaps you don’t notice the well behaved ones. They just blend in. My kids were especially intolerant of kids that weren’t being well parented at restaurants. It really got on their nerves.
In life we have room for all kinds of restaurants and I’m sure you can find ones where kids are discouraged as I was able to find ones where they were welcome. When we went to Atlantis for example a couple places were adults only, we just didn’t go there. I usually find if kids aren’t welcome I don’t like the ambiance anyway.
