Spanish tour operator Hidden in Spain is extending its 15% commission on all preplanned tours through Aug. 31.
"We work with travel agents to take care of every aspect of a vacation in Spain, from accommodations to ground transportation and domestic air, to excursions, to sight-seeing and all activities," said Hidden in Spain founder Luis Fernandez de Vega. "Guests can travel on their own or with one of our knowledgeable, English-speaking guides."
Tours focus on the Camino de Santiago pilgrim routes, a World Heritage Site and a popular way to see the country's smaller towns.
Camino de Santiago options include a weeklong, customizable walking and hiking tours, cycling routes and horseback riding.
