Going to Disney on Friday for 6 days. We have park hoppers. My boys are 19 and 14. I am wondering at what age do you feel comfortable allowing your kids to roam the parks without you? At what age would you allow them to hop to a different park? If I knew they would stay together I would have no issues. But they are complete opposite that probably won't want to stay together. Of course my question is primarily about the 14yo. TIA.
