Daily Mail shared photos of the resort the Royal Family is staying at. Some of the photos include the open-air dining gazebo where the family will eat for the party, the pool area where the party will take place, and the beach that is just a few feet from the garden where the family can snorkel in the crystal-clear Caribbean Sea.

According to other travellers on their flight, Prince George was "impeccably behaved" as he entertained himself with soft toys for the duration of the nine-hour flight.
