According to me it could be someone traveling without money, maybe the following can help someone who want vacation without money, this is based on my bagpacker friends experience:
Bring your own food, try to bring food that can be stored long, in accordance with the planned holiday time.
Ride a free vehicle
in some places sometimes available free transportation. or if you can not get a passing vehicle by asking him politely.
Stay in the open or in public facilities.
A Muslim friend of mine he once traveled by staying in a tent he brought himself. or if you are traveling look for a place that can stay for free for example in a relative's place.
When it runs out of money, then look for temporary jobs to make money.
Learn to process food from materials - materials that exist in nature. such as processing various foliage, fruit and wild tubers into food.
Prepare physically and mentally strong if you want to vacation without money.
