Best Smartphone Apps for Vacation Travel

A GPS-enabled smartphone is great for helping you make the most of your vacation time (as long as you don't succumb to the temptation of checking your work e-mail). Smartphones aren't the best devices for turn-by-turn directions as you drive (dedicated GPS devices are still the best and safest option for that). However, smartphones' maps and directions features are handy when you're walking. Here are some additional apps I recommend for vacation travel:
-AAA Discounts: Pinpoints your location and discounts nearby.
-FlightTrack live flight status tracker.
-Zagat Mobi works with all Web browser-enabled smartphones.
-The Weather Channel iPhone app.
-Telenav GPS Navigator for Android OS phones.
-Garmin Mobile for the Blackberry.
