What does a soon-to-be single lady with more cash than anyone could ever spend do amidst a divorce? Party. While working out the details of their split, Melinda Gates reportedly left husband of 27 years, Bill Gates, in Washington while she lived it up on a luxurious vacation to Grenada. This was no ordinary vacay, though. Melinda rented out the private Calivigny Island for $132,000 a night in March, bringing just her three kids and their significant others, according to TMZ.
