Exchanging your home with other people all over the world is BY FAR one of the best things you can do to travel for free. You save not only on accommodations, you also can cook your own meals instead of going to restaurants all the time. And to top it all off, staying in a home exchange through HomeExchange.com gives you a better chance to experience a destination like the locals do.
If you need to buy inexpensive travel insurance from a reputable company, look no further than World Nomads, the standard insurance company that independent, budget travelers use.
If public transportation isn’t really workable for where you are visiting and you don’t really need a rental car full-time while you are there, then you should seriously consider Zipcar, the world’s leading car-sharing network.
Learning at least some of the language of the the country you are going to visit is always a great idea. The locals love it, and you always have a better overall experience on your trip. Every Day Language Guides are a great and inexpensive way to get you on to the level of fluency that you are looking for.
