I’m planning a travel to Vietnam with my elderly parents and would be staying in Ninh Binh for two days. We’re four of us, so would need a cab to move around. Do you suggest hiring a car for sightseeing for two days, or if we take Grab as and when required, it will suffice? I don’t want to spend a bomb in transport unnecessarily, and cycling and scooter are not options to get around because of parents.
