When seeking to economize on an eco-vacation rental, search for a “self-catering” property, ideal for groups of up to 10 people who do not need to be waited on.

“Clubbing together for a group holiday can be a great money-saving solution, particularly for those with young children,” observes Justin Francis, cofounder of ResponsibleTravel.com, which has benefited from the trend. “Kids have their friends around them and parents can take turns babysitting. You’ll also save money on food and can share the cooking.” Many types of accommodations are available; working farms are particularly popular.
