Summarize this article in one sentence.
Different airlines can offer widely variant prices for similar flights, so be sure you shop around if you’re planning to fly. Remember that booking a flight and hotel together may save you money if the website offers specials or discounts. These websites often compare flight prices from different websites for you, all in one place. While flying is the quickest way to travel long distances, other options such as taking a train or bus or even renting a recreational vehicle may be less expensive and more environmentally friendly.  They may also be more fun, particularly if traveling with children. Reaching your destination is only one transportation consideration.  Once you have arrived in the area, you will need to figure out how to get from the airport, train station, or bus station to your hotel.  You may also have plans to travel locally while on vacation.  Call the concierge at the hotel you’re staying at and ask whether the hotel offers complimentary or reduced-fee shuttle service to and from the airport.  If they don’t, ask for any advice on local ground transportation. Rent a vehicle if you will need to get around a lot once you have reached your destination.  If you’ll be doing a lot of sight-seeing in areas that are spread out, a rental car will be a better option than taxi services.  Be sure you know your hotel’s parking policies and fees. If you don’t plan to leave your destination once you get there (for example, if you’re staying at an all-inclusive resort), you may not need a rental car.  Consider a taxi or shuttle from the airport instead. If you are going to an urban area, search online for the city’s public transportation options.  Areas with subways, trains, or bus systems often offer daily or weekly passes that are much cheaper than rental car fees. If you’re planning to drive to your vacation spot, be sure your car is up-to-date on basic maintenance.  Check the air pressure in the tires. Change the oil if it has been 3 months or 3,000 miles since the last change. Be sure that all essential functions are in good working order: check wiper blades, headlights and taillights, brake pads, hoses, and belts. Be sure you have a spare tire and working jack.

Summary:
Compare flight prices. Find a flight (and hotel) booking website if you plan to fly. Consider alternate transportation options. Consider all transportation needs. Perform scheduled maintenance on your car.
