I've heard of countries requiring two blank facing pages, but never 4 blank pages.


I looked it up at the Ecuadorian's US embassy website and they said that the entry requirements are the following:


VISAS - Visas up to 90 days (VISITOR) - Ecuador welcomes tourists and travelers from every country. United States citizens traveling to Ecuador for tourism, business, studies do not require a visa unless they expect to stay in Ecuador for more than 90 days in one calendar year (that is, 90 days adding every entry in one year). The only travel requirements are 1) Valid passport for more than 6 months. 2) Return ticket (for air, land or sea travel) 3) Proof of economic means to support yourself during your stay in Ecuador (may be asked by Immigration authorities)
