If you don't have a rental agreement in place, then the costs for travel is largely from flight travel. And many places locally are easy to fly for just several hundred $. If you have more of a budget, you can travel overseas in relatively cheap economic countries. It can be done if you plan accordingly within a budget.

Also helps if you are solo, and can cook. And I also think it's a great energy recharger and helped me when I was burnt out.
