Planning a trip is only the beginning. While TripAdvisor has provided airfare, hotel and restaurant tools through two apps, TripAdvisor and City Guides, travelers have had to turn to other sites to document their trips.

Recently, the granddaddy of travel sites added a suite of features to City Guides for Android, providing both check-ins and the ability to post photos. The update, adds online capabilities so that travelers  can check in, take photos, add comments and then share their adventures with friends on Facebook, on-the-spot with an Internet connection.
