Bill Gates -- My Summer's WAY Better than Yours!

Did you play tennis off the coast of a fancy island today with your family before being helicoptered back to your yacht? No? That's because you're not Bill Gates.

Gates -- along with his wife Melinda and their kids Rory, Jennifer and Phoebe -- knocked a few balls around in Porto Cervo, Sardinia before being flown back to the massive yacht they're renting.

After that, the family went through a rack of wet suits (because who doesn't keep their wet suits on a clothes rack?) before taking a dip in the Mediterranean Sea and hopping on jet skis.
