Visas are sometimes required, or in some cases other charges must be paid, for example for reciprocity fees or tourist cards.
Flights, cars and tours can be booked online at www.lonelyplanet.com/bookings.
Bus Extensive services throughout the continent, except for the Amazon. You'll find reclinable seats (and super-powered air-conditioning on long hauls).
Plane Useful for crossing immense distances; can save days of travel; prices are generally high, but airfare promotions are frequent.
Car Useful for traveling at your own pace, though cities can be difficult to navigate and secure parking is a must.
Boat Slow, uncomfortable, but brag-worthy transport between towns in the Amazon, with trips measured in days rather than hours. You'll need a hammock, snacks, drinking water and a high tolerance for boredom.
Train Limited networks, generally geared toward tourists.
