Now days, it is very good business idea and it makes our travelling very smooth as per our budget. Once I booked ticket of AC Bus to visit some where and I got very good offer by these travel agency as compare to do it by my own way. And it helps me to get hotels over there according to my budget and after I reached to my destination they call me back and asked my feed back and so that they can upgrade themselves. But there is so many agencies are there who just want to make money.
