Generally, I was with my family in Dubai last year. I have noted that without the rental car it wasn't comfortable to get around the city. So, I recommend you rent an SUV. Unlike smaller cars, SUVs provide ample space for usually up to 7 passengers. By the way, my recommendation for you is to hire a vehicle here https://full-size-suv.com/ When I was in Dubai, I rented the car only from this company.
