If you have more time, Mumbai has several other landmarks such as the Chhatrapati Shivaji Terminus, the Haji Ali Dargah, and Sanjay Gandhi National Park. In Ajanta-Ellora, you can add Aurangabad Caves and Grishneshwar Jyotirlinga Temple to your list. Consider wearing comfortable shoes and clothing as you'll be doing lots of walking and climbing. Please check the weather forecasts before visiting. If you have less time, skip Bibi ka Maqbara and Daulatabad Fort and spend more time at the Ajanta or Ellora Caves.
