1. Accommodation is going to be cheaper for you.
Now, I’ve only used Workaway and HelpX as a source for my work exchanges. (Something about the different website layouts for each country’s WWOOF page is displeasing to my eye, and I don’t really care for children.) But each host only expected me to work an average of five hours a day, five days a week. In exchange, I’d get a bed to sleep in and at least breakfast, sometimes lunch or dinner. Not a bad deal, right?
