ine, call the airline with requests for different flight options, hub cities and partner airlines to get the flight you want without burning through your miles. Rental cars and shuttles 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. Free lodging Frequent-flier miles are great for other free vacation travel options, including free lodging. While you're typically restricted to major chains, they can be used for thousands of hotels nationally and internationally. But that's not the only way to get a free place to stay. Websites such as HomeExchange.com are safe ways for you to trade living spaces with someone. If you have an apartment in New York and want to exchange it for one in Paris for a week in the spring, that's no problem. Looking for a beachside condo in exchange for your home next to the Rockies? That's a possibility, too. Even better, you could get free travel perks that not even the best hotels can match, says Keghan Hurst, spokeswoman for HomeExchange.com. "A lot of our members will include access to their vehicles, bicycles and even boats," she says. "Everything is negotiable." If you're not interested in exchanging spaces, CouchSurfing.net helps people find a place to crash for free, with nothing required in return but good manners. Free grub Most three-star hotels offer a complimentary breakfast with your stay, and some go even further. For example, the DoubleTree hotel chain gives free cookies to guests and many Hampton Inns provide free popcorn. Some hotels that cater to business travelers, including many Starwood Hotels, offer complimentary happy hour drinks and hors d'oeuvres on weekdays. It's not just the chains that offer this free vacation travel perk to their guests, says Mary White, founder of BnBFinder.com, a bed-and-breakfast information website. "Many bed-and-breakfasts offer bottomless cookie jars, snacks and beverages," in addition to the morning meal, she says. But if you can't survive on breakfast, snacks and happy-hour finger foods, consider a working vacation with World Wide Opportunities on Organic Farms, or WWOOF. You volunteer your labor and owners offer free lodging and food. Free tourist attractions Museums are a favorite attraction for many visitors, but getting in can cost an arm and a leg. For example, New York's Museum of Mo
