They're leaving George behind for some of it.
At one point, George will be 500 miles away from his parents, while they spend two nights away for a day of wine tasting and white-water rafting in Queenstown, NZ. He'll be well cared for by his Spanish supernanny.
Will and Kate booked an entire resort for a romantic night away.
Will and Kate booked an entire 10-suite resort to themselves, reserving a discounted rate, for their time away from George. It's rumored to cost about $11,000 a night.
The trip is all over social media.
