There are 16 international airports and 35 domestic airports serving Florida so it's easy to get to all the major destinations. Shuttle buses generally link the airports to the major resorts and hotels in the surrounding area, and some resorts and hotels offer free shuttle transfers.
Car hire is available at all airports, and is a popular way of getting around Florida. If you are heading to Miami, Orlando, the Tampa area, Polk County or Volusia County you can also take advantage of the public transport systems. They all have bus networks, Miami has a metro system and Tampa operates a trolley network. There are various other small scale networks operating throughout the state and it may be worth checking what facilities your destination can offer. It is also worth checking what transport is offered by your hotel in Florida as many run free shuttle buses to the main attractions in the area.
Roads in Florida are good, so most visitors to Florida choose to hire a car, especially when they're planning to tour the region's theme parks as the distances involved can be large! For travels further afield there are a few options if you don't want to hire a car. Domestic flights make for a quick and easy way to travel, particularly if you have a greater distance to cover. There are a few train services offering long distance and interstate travel. They depart from Orlando or Miami, but the coverage is limited. Greyhound buses operate throughout Florida and beyond and are a good option if you're travelling long distances on a budget.
