You might not think a homestay is for you, if privacy is what you want on vacation, but it really is worth spending at least a couple of days of a vacation in a homestay - if not the whole shebang. Because, take it from us, homestays are vacation highlights. Apart from supporting the local economy, you are also embracing the notion that we, as visitors, are guests in a country and that the people who live there are our kind and generous hosts. In Kerala, you can go on a homestay tour, seeing different aspects of this stunning state but staying with different families throughout your stay. In Vietnam you can trek from home to home in the Tonkinese Alps near the Chinese border, with superb home cooked food at the end of the day to reward you for all your walking. Food is also a big element of homestays in Costa Rica, often hosted on farms where beans, corn, and dairy products are a very much part of the culinary experience. They're a great way to improve your Spanish, too.
