Hi, My husband and I intend to go to the Salar de Uyuni, from San Pedro de Atacama, on January 15, 2013 and returning on Jan. 19. We researched several agencies that make the tours and the best ranked were the Cordillera and Ruta Verde, the latter has oxygen balloon and satellite phone in case of emergency. The cost of the trip its around US 2200 per car, that can be shared by 4. We want to know if any couple is interested in sharing the tour with us? Thank you
