The World's Newest Budget Airline

Nothing ruins a great trip like getting sick on the road. We found out the hard way during our family vacation to Italy this summer when my sister and I caught a nasty headcold and  found ourselves in the local drugstore trying to impress upon the pharmacist in a foreign language that we were looking for cold medicine.

Last Oscar season, we revealed our top picks for the most travel–inspiring films of the year. But why should the big screen have all the fun? This year, four television shows are inspiring a serious case of wanderlust. Make sure to check this list before you make any plans: Not every show is filmed where it’s set! Homeland Showtime, Sundays at 10 p.m. Without giving too much of the twisty plot away, season two of the Emmy–winning political thriller takes certain characters to Beirut amidst political turmoil. Instead of Lebanon, the show filmed in Tel Aviv and Haifa to capture the feeling of an old Middle Eastern city—think winding alleyways, sun–bleached buildings, busy marketplaces, colorful garb. (Check out the show’s YouTube channel for on–location videos: Part 1, Part 2, and Part 3.) Fun fact: The American version of Homeland is actually based on an Israeli hit called Hatufim (“Abductees”). Survivor: Philippines CBS, Wednesdays at 8 p.m. Season 25 of the reality juggernaut brings the castaways to the Caramoan Islands, an archipelago off the eastern coast of the Philippines. The islands have already hosted a number of international versions of Survivor, and it’s easy to see why: The mix of sandy beaches, waterfalls, lush green hills, and dramatic rock formations will have anyone hoping to get stranded for a few days. Revenge ABC, Sundays at 9 p.m. The glitzy soap opera charts one woman’s quest for, well, revenge in the high–class world of the Hamptons. But the show’s creators may be just as deceptive as Emily Thorne’s (Emily VanCamp) enemies: The series is not shot on location on Long Island! If you’re looking for the beach houses featured in the first season, you’ll want to head to North Carolina, especially in and around the beaches of Wilmington. Exteriors of Emily’s house from the series pilot were filmed in the nearby town of Southport—but all subsequent interiors are filmed on studio lots in California. 666 Park Avenue ABC, Sundays at 10 p.m. Looking to stop by the creepy apartment building in ABC’s new horror drama? If you head to 999 Park Avenue (near East 84th Street), where the fictional Drake apartment building is set, the neighborhood is reliably posh—but you won’t find the shows stars, Vanessa Williams or Terry O’Quinn, anywhere in sight. To see the actual Beaux–Art exteriors, you’ll have to cross Central Park to the Upper West Side: The Drake is actually played by The Ansonia, which is located at 2109 Broadway (between West 73rd and 74th Streets). Which new or returning shows have you packing your bags for a TV–inspired vacation?

Their names—Advantage, ACE, E–Z, Fox, Payless, Triangle—don't exactly ring a bell. In fact, you might not realize they're in the rental car business. Yet in recent years, as the rental industry has boomed, regional and off–brand rental companies have been making more of an impact, thanks to Kayak, Priceline, and other websites that include lesser–known (and less advertised) companies in their searches. Are they worth taking for a spin? In general, the answer is yes. Regional companies typically offer the same cars as their bigger competitors and at a better price, says Neil Abrams, president of Abrams Consulting Group, which tracks car rental trends. Prices vary widely depending on company and location, but you can save up to $20 per day by going off–brand, says Abrams. For example, Advantage Rent a Car, a subsidiary of Hertz with more than 100 facilities worldwide, will book you a Chevy Aveo or Cobalt for under $130 a week at Hartsfield–Jackson Atlanta International Airport in mid–September; an economy car from Enterprise at the same location will run you more than $250. Some of these smaller companies also have loyalty programs just like the big boys. Members of Payless Perks Club, for example, can save up to 5 percent on rentals. E-Z Rent-a-Car, which has 36 locations worldwide, gives its program members up to 2 percent off all rentals, and its Facebook fans get 3 percent off on top of that. On the other hand, these smaller companies sometimes aren't partnered with airlines to offer frequent–flier miles. The booking process—reserving online or on the phone—will be the same as you're used to, and insurance rates will be comparable to the major agencies, too. But ask if there's a fee for returning the car to a different location—or if you can even make a one–way rental at all. Some indie companies don't have storefronts nationwide, which could limit potential drop–off choices. Overall, inconvenience is the price you'll pay for a better deal. There could be longer lines at check–in and longer wait times on the phone. But not all indie customer service is under–whelming: ACE Rent a Car ranked highest in customer satisfaction in a recent J.D. Power and Associates survey, beating out Avis, Hertz, and the rest. One recent renter told us that he experienced long lines at the LAX counter of Payless Car Rental, which has 80 locations worldwide, but he saved $100 over four days compared with a major agency. "For the price, I'd put up with that slight pain again," he says. You may also have to let go of easy airport access. Triangle Rent a Car, a family–owned company in the Southeast, picks renters up at four airports and shuttles them to offices that are up to 20 minutes away. Research your company's location before you fly: Fox Rent a Car, for instance, has 20 U.S. offices, but some are not located with the other agencies and others are off–airport entirely. Think of it as the new rules of the road: Trade a little time for a decent chunk of change. —Hannah Wallace MORE FROM BUDGET TRAVEL: Introducing Budget Travel's Ultimate Road Trips App! 5 Classic American Drives 7 Tricks for Getting Gas for Less
