When I plan a vacation, my first stop is TripAdvisor. I love their overviews of vacation spots and thoughtful reviews of specific hotels and attractions written by users. For example, when my family stayed in Flagstaff, Arizona, we knew to bring earplugs because reviewers mentioned that the train runs right through town night and day! TripAdvisor links to booking services too, with searches for hotels, flights, and even vacation condo rentals. The site adapts easily to your mobile phone Web browser. Or, download the TripAdvisor app for Android, Palm Pre, or iPhone [http://www.tripadvisor.com/InfoCenter-a_ctr.mobile].
