This sounds immediately quite strange to me,,, but there is probably something in there that we are not aware of. Five year old kids can maybe GO inside a casino but I doubt the employees would actually entertain a kid walking inside it right?
That has to be a very bad wikipedia entry:)
Even if they allow it I will not allow my 5-year-old kid to spend times in casinos there are a lot of bad things that your kid won't want to see in casinos, and the kid will learn that it's ok to spend your parent's money in gambling because they not have the means to support themselves maybe it's just a bad entry, someone has to confirm this.
