Regarding boarding school costs it probably depends on the quality of school, but yes they are genuinely expensive. My sister went to one as a scholarship kid for her last two years of high school and it cost about as much as going to a fancy private college (albeit the one she went to was sort of a renowned arts school, so a lot of celebrities and other rich people sent their kids there). Still, the cost of a yearly tuition probably equates to probably between one or two Roy O D cruises.
