For some reason a multi-pass isn't offered on the Greyhound website but if you go to this site, you can purchase a 1 week, 2 week, 1 month or 2 month option for unlimited trips via bus: Log In The website looks to be advertising for visitors from New Zealand however, it is for continental U.S. travel and parts of Mexico and Canada. If you compare one way trips across country via air, train, bus, and car rental the rate of $577.00 for an unlimited one month ticket is not that bad. Does anyone have any experience using this or like services?
