As I sat on a bench at Legoland with a napping baby, a grandmother sat down next to me. She told me how she and her husband try to take their grandchildren on vacation each year during September. “It simply is the best month to travel,” she told me. I had to agree, but then I said, “It will be hard when they are in school.” She looked at me incredulously and said, “You’re the parent. You can take them out of school whenever you want to.”
