READERS' CHOICE: Which Airline Has The Nicest Flight Attendants?

Weddings, reunions, graduations, new babies, business trips. Are you taking fewer leisure vacations because of the time and money you devote to obligation travel? According to a recent survey commissioned by Hotwire.com, 41 percent of traveling U.S. adults spend the majority of their vacation budget on obligation travel. And 89 percent of respondents said they would take more leisure trips if they had the time and the money to do so. For its American Travel Behavior Survey, Hotwire commissioned Harris Interactive to conduct an online survey of 2,127 U.S. adults from July 27-29, 2011. According to the survey, 94 percent of respondents said that they would take one more trip than they already had planned if they could afford it. The solution, suggests Hotwire, is combining the obligation travel with leisure time. Work sending you to a conference in Orlando? Bring the spouse and kids so they can enjoy some time at the local theme parks. Family reunion back home? Try to tack on a weekend getaway for some time away from everything — and everyone. But there are advantages and disadvantages to this approach. If it's a personal trip, a family event or gathering, travelers still have to find the time and money to get there, and any extra time spent away is just that, more time and money. That said, if you're already paying for a flight somewhere, it might be more economical to just add on some extra time rather than book an entirely separate flight and vacation elsewhere. If there is a business trip element, there are potential savings to be had on at least one person's transportation costs and possibly the accommodations, depending on the business trip. But then, the person working might be unavailable for part or all of the trip. What about you? Do you feel like most of your travel is devoted to obligation trips? Do you try to turn some of those trips into potential leisure getaways? What, in your opinion, are the advantages and disadvantages in doing so?

As Facebook's popularity booms, everyone's coming out with new booking and travel-planning tools to win your trust—and business. But which Facebook-powered tools make your life easier? 1. THE PROBLEM: Your loved ones want to follow along "virtually" while you travel, but you don't want to spend your vacation tied to your e-mail and cell phone. THE FIX: Tap into Facebook's power to update your family and friends automatically. Last fall, Wipolo, a travel dashboard, integrated with Facebook as one of the first free Facebook "apps." Click a button, and this app semi-automatically tells loved ones where you are in your trip. The tool shares your itinerary (from booking confirmation emails that you forward to it) and updates the specific list of friends you select, via their Facebook feeds. 2. THE PROBLEM: You have an upcoming milestone (like an important birthday) that you would like to celebrate with a vacation. But you need help affording your dream trip. THE FIX: MyTab.co, appearing last July, lets you share your dream destination with friends through Facebook and enable them to chip in to cover the cost of your tab via PayPal. 3. THE PROBLEM: Getting recommendations for hotels and restaurants at your destination used to be easy: Just post a status update requesting help. But now there is so much clutter in freinds' news feeds that your call for help may go unread. THE FIX: Add the free Facebook app. Trippy (which launched last September) posts your queries directly on their walls, which is more likely to be read by a Facebook user than random every item on a news feed. Even better, Trippy savvily targets which of your friends might have relevant recommendations. It picks the friends to contact after analyzing all of your friends' public profiles to see if they may know something about your upcoming destination. (Maybe they've taken photo at the destination you're planning to visit, which is a telltale clue.) One final note: Facebook is a fantastic tool for planning last-minute trips. To get discounts and giveaways to real-time, 11th-hour travel deals, consider "liking" or "friending" travel deal aggregators such as Airfarewatchdog, FareCompare, or Best Travel Deals. Members of hotel programs can benefit from exclusive Facebook offers by "liking" those company's Facebook fan pages, such as the especially active ones for Hilton HHonors and Starwood. We've seen especially worthwhile offers on the pages of loyalty reward programs in the past month. For example, yesterday, the Facebook page for PriorityClub—the loyalty program for major chains like Holiday Inn and InterContinental—touted a 24-hour sale on hotels, with a dozen properties up to half-off last-minute bookings.

It was announced this week that the national average for a gallon of gas is $3.57, with analysts projecting $4.25 gallons this summer. Whither the road trip? Californians are already seeing average prices over $4 a gallon, not a good sign for those considering a Route 1 adventure. My mid–size rental car drank up more than $80 worth of gas during a weekend road trip between New York and Boston, and that was only four hours each way. I can't even imagine what it would cost to go cross–country. And it's not just road trips that can be affected—cruise lines like Norwegian reserve the right to add a surcharge to fares (even those already paid in full) if oil costs more than $65 per barrel at the time of sailing. It's currently $105 a barrel. Does sticker shock at the pump have you already thinking about alternatives to summer road trips? Or is the journey worth a few extra bucks? You can always find ways to save. See our tips here. MORE FROM BUDGET TRAVEL One-Tank Escapes for 7 Cities Beautiful Lakeside Drives How to Do America's Most Scenic Drive—Without the Traffic
