K444404 seems not to work in Chile or Ecuador. At time of reservation it provides a good discount, but the reservation appears at the rental counter with no price at all. Even with a print out in hand, the K444404 rate was not accepted, although other discounts were offered on the spot. [Just a hint: in Chile, Alamo is very reasonable; in Ecuador, most hotels have cars with drivers that are far cheaper and more convenient than a rental car]
