Prince William and Kate Middleton ended their visit to Cyprus, where they spread holiday cheer to military families who will be away from home this Christmas, by officially opening the Oasis recreation center.

Spotting the bright yellow couches in the room, William teased the men to “keep the pizza off the sofas!” His wife playfully volleyed back, “You're a nightmare with that!”

Former Royal Air Force pilot William recalled the tokens he would use to make 15-minute calls home when he was serving time away.

During a walkabout outside the Warrant Officers and Sergeants' Mess, Kate chatted with well-wishers – and revealed that 7-month-old son Prince Louis is already working on his royal wave.

Kate also disclosed she had tried to show her older children, 5-year-old Prince George and 3-year-old Princess Charlotte, the festive treats laid out for military families at Kensington Palace for yesterday's party when they arrived home from school and nursery — but they were too late.

Still, George was already looking forward to something else, William shared with a group of pilots.
