From rental cars to shuttles and public transportation, you'll need to get around once you reach your desired destination. Consider these free vacation travel options to get from point A to point B without spending a cent.

Many airport hotels will offer shuttles to and from their site. Some Las Vegas casinos are happy to send a shuttle to pick you up from the airport. If you spend time at a hotel close to a major tourist attraction -- any of the Disney sites, for example -- nearby hotels often provide buses to the site.

Transportation to and from the airport may be packaged in free with your all-inclusive subway or bus pass, too. So don't wait to get to the city to buy your daily or weekly pass, says Dave Dudar, an independent travel consultant in Atlanta.

For example, while you can easily pay $40 in cab fare to get from La Guardia Airport to Manhattan, you can avoid that cost by taking inexpensive mass transit into the city.

And don't forget that your frequent-flier miles can give you wheels, too. Your miles can be redeemed for rental cars from most major companies.
