Planning Agra in one day can be challenging, especially with train schedules and crowds. I found that a Same Day Taj Mahal Tour by Car offers more flexibility and comfort. Check details at https://indiatourtaxi.com/day-trip-to-taj-mahal-by-private-car.html. For small groups, Swift Dzire on Rent is a practical option: https://indiatourtaxi.com/swift-dzire-on-rent.html. Has anyone tried this route recently?
