My wife and I are traveling to San Jose in January on a one-way ticket with the thought of traveling around Costa Rica for two or three weeks then taking a bus overland to Panama. We then plan traveling Panama for the same period and exiting through Columbia. I looked at a website which states a outward bound ticket (either air or surface) is required (upon entry?) into Costa Rica. Does anyone know of exceptions or something I can do to preclude buying a ticket before I arrive? The whole idea of this trip is to have the freedom to explore at leisure without having set artificial departure times in advance. Any help would be greatly appreciated. Jim R.
