Going on vacation, but want to do it the least expensive way? Well, get ready to get app-y! There are some fabulous apps that can save you boatloads of money on vacation.

KAYAK is a great app to research the least expensive flights, hotels and car rentals. And, get this…after you book, you can track your bookings with a simple management feature, and it also has an integrated Twitter feature.

If you are driving to your vacation destination, don’t do it without GasBuddy. GasBuddy is a running list of pas prices in real time throughout most of the country, and in this day and age, is something you just can’t be without.

If you want a second opinion, Yelp can give you thousands. Yelp offers thousands of reviews for everything from entertainment to retails establishments. It also offers a very cool feature that shows restaurants by their per plate costs, which is absolutely priceless for those traveling on a budget.

The Meal Ticket app helps in your search for restaurant coupons by area, and HotelPal and Hotel Tonight are great for booking last minute hotel deals. If you are traveling in another country, XE Currency can calculate current exchange rates for you. There is also a Transit App that provides valuable information about nearby transit lines, and Groupon searches for deals on fun things to do and tasty things to eat so you don’t have to.
