From Delhi, its easy to make a day trip to the Taj Mahal. It will not impact your pocket that much as you can manage it within rs 1000 minimum. All you have do is to group your friends and drive. I took 3 of my friends there. 2 Bikes 4 people. Both guys were driving and we two were enjoying the view. We started our trip early morning at 6 AM and returned back to Delhi at our place around 9 PM. Here is my experience which may help you to plan your trip.
