I tend to disagree. My kids are very little 2 and 4 y/o so I am not even considering this yet and do realize there will be a time when I will be faced with this decision. I know a retired police commissioner whom has been on the search task force for missing children in - yes, WDW. I won't go into detail, but it can happen anywhere.
My personal beliefs are to keep a close watch on them for safety and even weirdos and pedophiles buy tickets to WDW. This is one place where parents DO let there guard down more.....Quite scary, IMO.
At 2 and 4, I would never have thought my kids would be self-sufficient enough to be alone anywhere much less Disney.
Fastforward 10 years....my kids have grown up!!!
(not directed toward PP, just my own feelings on the subject): We are aware of the dangers of the world, but with all due respect, there will always be missing children, but the likelihood that they will be MY children is very small. I wish that it would never be ANYONE'S kids, but the odds of my kids turning up missing in DW is very, very small. We hear about the stories of kids who do go missing *because* it is so rare.
That being said, I also thought that way about my kids walking around in the neighborhood until a 17 year old boy was hit by a car and died at the scene. It was his fault...he had earbuds in and rolled out on his skateboard in front of the car of a 38-year old father who was NOT speeding, it was about 3:30pm, in daylight, and the man stayed with the teen and even followed him to the hospital because the boy did not have ID on him and nobody knew who he was or how to contact his parents. It was awful. It really hit home that anything can happen, at any time, and it does scare me a little to let my kids walk home from school/etc.
But...(again! LOL) I have to. I have to let them grow up and experience things, and make choices (ie. do I cross now, or wait for that car that is WAAAYYY down the street to pass?) I have to give them to freedom to learn on their own because I have no plans to follow them to college or live with them when they are married or go with them on a job interview so that I can always make sure they are OK. My job as a parent is to raise them to have the confidence to one day become independent, responsible, respectful adults, and like it or not, there will be a day they will be old enough to go off on their own at DW.
SO, my answer is, my kids are (almost) 14, (almost) 10, and 8. I would let them go together anywhere at our resort together alone, and I would let them go together to a ride alone while I sat on a bench or shopped somewhere close. If my oldest had a similar age sibling, I would let them go off alone for however long we were in a park for the day as long as they checked in every now and then. My rules would be that they have to stay in the park and cannot take transportation out of the park without us.
When DS is 15-16, he will pretty much be able to do/go wherever he wants whenever he wants (at WDW LOL...not in life overall!!

)
