With all the U.K. safari parks I've been to in the last few years, you have the choice of whether or not to take your car into the monkey reserve or take the road that bypasses it. After losing my trim and windscreen-washer-nozzle to the Rhesus Macaques at Longleat some years ago I generally opt now to avoid monkey reserves (Rhesus Macaques may not be quite as bad as the baboons that they've largely replaced, but they are still pretty destructive). The only monkey reserve I do still take my car through is the one at Woburn Safari Park. This is a lovely reserve, populated by Barbary Macaques, Patas Monkeys and Drills (and Bongo), and they rarely seem to cause much trouble. Whilst on the subject of Woburn, in the early years visitors were allowed to mingle with the antelopes, zebras and giraffes, as photos in the early guidebooks testify - something which would never be allowed today (not in the U.K. anyway). It always annoys me when you see characters in films remarking: "Oh it's a herbivore, a plant-eater, it's harmless, there's nothing to fear." The script-writers of such films have obviously never encountered an enraged zebra, buffalo, elephant, rhino, deer stag, hippo, etc.
