Take a backpack and stock it with wet tissues and water
While the desert safari will definitely have free-flowing water, I’d recommend taking a bottle of water for the journey. It takes around an hour to drive out to the desert and it’s always better to have your own bottle of water atleast for the journey from and to the desert. Another thing, not a necessity but an easier choice, ditch your fancy purses for a sturdy backpack. It’s going to be so much easier to enjoy yourself when you’re not worried about minding your purse.
