From finding a good place to eat in the airport to finding a hotel room when your flight is delayed, Jim Greer from AT&T explains how to use travel apps to make vacations a little easier.

Yelp
You're in a new city you know nothing about and you don't know what to do next. Yelp can help with anything. Restaurants -- read reviews of the highest rated. Coffee shops -- which ones have Wi-Fi. Hotels -- which ones have never housed a serial killer. Car is spewing brake fluid -- which mechanics won't rip you off.

GateGuru
Yes, GateGuru can tell you where to find the restrooms in Terminal 2 at O'Hare and where to find truly good clam chowder at Sea-Tac, but what makes this app special is its ability to help travelers find the shortest way through security. "During the summer you could be an hour or more going through security," says Daniel Gellert, co-founder and president of New York-based Mobility Apps, which launched free app GateGuru. The app relies on 400,000 users to provide real-time information for 125 airports -- 30 of which are overseas. The app provides maps of airports, lists retailers and restaurants, and allows other users to post reviews and photographs.

HotelTonight
Speaking of stranded, this app could save you from spending the night on the airport floor should a summer storm ground your flight. It works equally as well for those on a road trip or travelers inclined to book getaways at the (very) last minute.
One important note about HotelTonight is that it's good for same-day hotel bookings only, and you can't book until noon. But the savings are serious.
