I have always travelled on Budget when it comes to a new destination or a place. I would like to travel to a new place and explore the place rather than spending for stay and food.
Hence, this is one step which I follow during my visit to a new destination where I tend to do domestic travel at night.
If you want to explore a place and visit the next domestic destination, book a night train that departs to your next destination.
In countries like India, Thailand etc many trains depart to different domestic destinations at night and thus it will help you to save amount on your stay.
Trains are one of the major forms of public transportation which are generally cheap compared to bus and flights, although train travel takes longer time to reach the destination, you will pass across picturesque landscapes which is difficult to notice if you travel via bus or flights.
Bonus: If you book a night train in first class or second class compartment, complimentary meals would be provided thus you can even save on food expense.
