Android TripAdvisor: While opinions on TripAdvisor vary, for many it's like the Yelp of travel, providing reviews from other travelers and helping to narrow down and select where you want to stay and dine. This app, which has a native Android tablet experience, contains the reviews you've come to know TripAdvisor for as well as a restaurant, hotel, and airfare booking tool. Also available for iOS. Free
TripIt: This app has long been known as the king of the travel organiser space although I will admit I use it far less than I did back in the pre-Passbook and good airline app days. TripIt is the place where you can store your travel details like your flight, hotel, and car reservation and if you have the Pro membership ($49 a year) will give you live updates if the gate changes for your flight or if it's delayed. Also available for iOS. Free
iPad Orbitz: There are many ways to find a hotel, car rental, and flight so a way for an app or site to stand out is by offering great deals and an excellent search experience. Orbitz does both of these things and we think their hotel search is really a cut above the rest (thanks to the filters and UI) especially when the app is used on an iPad. Also available for Android phones. Free
Priceline: Fans of The Negotiator need not despair, there is a Priceline app. Of course you can always go to Priceline.com but the app is going to provide a much better experience especially when your data connection isn't stellar. Also available for Android phones. Free
Windows 8 Kayak: If there's one app that I refer to time and time again for flights, hotels, and car rentals, it's Kayak. I love the clean design and the fun search feature in the iPad app which lets you choose your originating airport and then will show you where in the world you can fly for under a certain price. Kayak also has a My Trips feature (on Android & iOS) which is a travel organiser like TripIt. Did I mention that there's also a native Android tablet app and it includes airport terminal maps (terminal maps are available in the Pro $.99 version of the iOS app)? Also available for iOS & Android tablets & phones. Free
Travel Everywhere: Want to search through all of the aforementioned travel search sites with one tap? Check out Travel Everywhere. Travel Everywhere lets you search for flights via Priceline, Orbitz, Travelocity, Kayak, Expedia, and TripAdvisor all from this one Windows 8 app. Free
