Who rented Sandcastle this summer? One source with knowledge of the deal says it's no one famous nor a company looking to do a big event, just a family willing to fork over $500,000 for their two-week stay.
Sandcastle is a 31,000-square-foot compound, which features a two-lane bowling alley, a skateboard half-pipe, a rock climbing wall and other amenities to keep the clan entertained.
