How do I get there? Rental Cars? Flights? Greyhound?

The Gainesville Regional Airport is a quick cab ride to downtown. They mainly use Atlanta as a hub. Check there, but Jacksonville, Tampa, or Orlando are usually cheaper.

Also, check out: Runways. It is a shuttle service that runs from Jacksonville/Orlando Airport to Gainesville and back daily. Pretty cheap if you book 4 folks together plus you can sleep in the A/C.

Gainesville also has a Greyhound station that is in walking distance from downtown or a short cab ride.
