School's out, which means it's time for a family vacation. Instead of paying sky-high airfare prices, consider taking a road trip.

According to a recent survey by Expedia.com of 2,341 adults, 50 percent of respondents said they plan to take a summer road trip of more than 200 miles this year. "The great American road trip is very much alive," says Christopher Elliott, a consumer advocate and travel writer who blogs about his family's vacations at AwayIsHome.com. "It's ingrained in our national DNA."

A family road trip is a rite of passage for some, but cutting costs without sacrificing the quality of the vacation can be challenging. If you're planning to hit the road this summer, here are some tips on how to book cheap lodging, find low-cost entertainment and burn less money on gas:

Take advantage of a gas rewards credit card. The odometer doesn't have to be your enemy. Paying with a gas rewards credit card puts money back in your pocket each time you fill up. Gerri Detweiler, director of consumer education at Credit.com, recommends the TrueEarnings Card from Costco and American Express, which offers an attractive rewards program including 3 percent cash back at U.S. gas stations and on gasoline at Costco on purchases up to $4,000 per year (1 percent thereafter); the card excludes cash back on fuel purchases at other warehouse stores like Sam's Club.

GasBuddy (available on Android, Blackberry and iPhone) can also come in handy. The mobile app takes recent reports from more than 27 million drivers to supply smartphone users with current gas prices at local stations so they can find the cheapest pump nearby.

Time it right. To find cheap lodging, travel during off-peak times, and avoid booking hotels during Memorial Day, Fourth of July and Labor Day weekends. If you like to plan ahead, search for deals on websites such as Hotwire.com, Kayak.com and Expedia.com.

There can be benefits, though, to being a spontaneous traveler, says Sarah Gavin, Expedia.com's director of public relations and social media. She says hotels often slash prices on rooms at the last minute to fill vacancies. You can find such deals on mobile apps like Hotel Tonight (available on Android and iPhone), which offers same-day bookings of up to 70 percent off at luxury hotels. Gavin says the best discounts tend to crop up toward the end of the season, since a number of hotels will try to make up for a slow summer in August.

Moreover, planned and spontaneous travel can complement one another. "If you do see a reasonable retail option ahead of time, go ahead and lock it in," says Pierre-Etienne Chartier, vice president of operations at Hotwire.com. But he recommends families continue checking discount websites as they get closer to their trip. If they spot a lower price, they can simply cancel their initial reservation and book the new room. "Just make sure you know the retail cancellation policies inside and out before using this strategy," Chartier says.

Get the car ready. The last thing you want is your vehicle to act up while on the road. Bill Sutherland, vice president of travel services at AAA, says it's crucial to take the car to a mechanic before a road trip. Make sure he or she checks the brakes, oil, coolant and warning lights – and don't forget to inspect the tire pressure. (According to AAA, only 17 percent of cars on the road have all four tires properly inflated.)

Consider renting a fuel-efficient vehicle if your car gets poor gas mileage. Packing light and unloading excess weight will also help burn less fuel, so remove any unnecessary items and consolidate luggage when possible.

Eat well. Road trips are full of unanticipated events. Driving poses a number of risks – traffic, a flat tire, a wrong turn – that can derail your ETA at various checkpoints, making restaurant reservations easy to miss. Fortunately, you can tap your smartphone to find cheap eats while on the go.
