And outsiders have no way of knowing how you made this work for your family.
I have a friend who turned late EMH into a new day for her kids. They would get up early, eat breakfast, and hit rope drop or Am EMH if available. Then they ate lunch at around 11. After lunch,they headed back to their resort, and swam. By 2 Pm the shades are pulled and the whole family lays down to sleep. The kids are given cereal when they wake at around 6 or 7 pm. Then they head to the night time EMH park. The kids are refreshed, and they usually play the night away.
When they do this, they sleep in the next day, and usually hang out at their resort relaxing, maybe hitting an in park TS for dinner.
It works for them, and it's really nobody's business what time other people's kids go to bed, especially when they are on vacation!
