Best Travel Websites
Manage Your Vacation: Tripit.com
Click Factor: After you book a flight, hotel, or car rental, just forward your confirmation e-mail to email@example.com and the service will input the information into an online itinerary for you. The site also sends you text or e-mail reminders to check in (which you can do from the site itself) and, for premium subscribers ($69 per year), updates on any flight delays or gate changes. You can easily add restaurant reservations and other excursions to your itinerary and share your trip information with fellow travelers, LinkedIn contacts, Twitter followers, and Facebook friends.
Drawback: If you change your flight or hotel reservation, you have to manually remove it from the site.
