This is all so interesting to read

. It got me thinking, and I realize that a lot of the differences in responses come back to how independent the child is required to be at home.
We live in the city, and kids start high school in 7th grade here (so 11 or 12 years old). At that time, they are expected/required to use public transportation (various combinations of subways and busses for 30-60 minutes each way) to get to school. They have to be able to think on the fly (subway line is down; bus is stuck in traffic; bus stuck in a snowbank) and change their routes/itineraries accordingly. They also have to be able to call for help/advice if necessary (hence the need for a cell phone). Neighborhood kids walk the 3 city blocks to the outdoor municipal pool in the summer starting at the age of 8 (as soon as they are legally allowed to go to the pool unsupervised).
Disney is a walk in the park (haha, no pun intended!) compared to home!
In the meantime, my best friend lives in a different city in a residential neighborhood. Her 13 yr old daughter has an 8 minute walk to her elementary school (eighth grade), with various friends who live along the way. She has never taken a city bus, hasn't seen a subway, hasn't been asked to babysit yet, and has no need for a cell phone. My friend's daughter is way more mature psychologically than my 13 yr old son; she just doesn't have the experience needed to feel confident with being let loose in Disney.
