We all know family vacation can be a bit hectic. Field Trip (Free, iPhone and Android) is great because you don't have to remember to use it. Instead of keeping your phone out and the app open waiting for something interesting to happen, Field Trip will alert you when you're close to something your family might like.
We tested out Field Trip in Chicago and liked that we could choose what kinds of "interesting" alerts we wanted. Categories range from historic places and museums to food deals. Our favorite though? "Cool & Unique". The kids will love it.
