Djokovic, who will face Malek Jaziri in the second round on Wednesday, enjoyed time with family and friends at Wild Wadi Waterpark and the Burj Al Arab Hotel.
Elsewhere, world number four Stan Wawrinka had the luxury of zip-lining across the fountains at Dubai Mall, while Spaniard Feliciano Lopez had perhaps the most exciting afternoon as he spent time zipping around in a Dubai Police Audi R8.
