Answering myself: I found a curious comment by
@LaughingDove about the place called Banyan Tree Al Wadi in United Arab Emirates:
Arabian Oryx in a playground! - ZooChat
"The main function of this place is a luxury resort though it has a few animals as there is a mini zoo type thing within the resort (I didn't actually stay there overnight - too expensive - I just visited during the day). Free roaming around the place are Arabian Oryx and Arabian Gazelle which congregated in areas where the lawns were watered to eat the grass such as in this playground."
I wonder how much space is there and how confined are the gazelle? Is this some version of an American park with semi-wild white-tailed deer, but on the desert and with gazelle?
