Athens has options for bus travel. Traveling by bus is cheap and convenient. The bus services in America cover both major cities and the smallest of rural areas. Greyhound bus services are the most popular, with a large number of bus stations. They operate usually round the clock, connect both cities and rural areas, and have a number of stops conveniently situated for passengers to embark and disembark. One can also opt for express buses with few or no stops in between. Other services offered include cafeterias and gift shops at many stop-off points. Other bus services may also be available in Athens, but nationally, this is the most efficient service available, though many regional players exist. One can buy one-way tickets, return tickets, group tickets, package deals and many more combinations that may be available in Athens. One must book well ahead of time, and be careful with luggage while traveling by bus.
