I'm traveling today to Calvin, Grand Rapids, MI (US) for the conference on Philosophy & Liturgy.
And I'm making this trip, with the help of Tripit.com. This web application is just amazing.
After setting up my account, I forwarded my flight confirmation emails to my account, added the conference events, car rental, hotels, and it collates and automatically sets up a schedule.
Then I can give a link to friends, family who can access the schedule, and have my details and contact info etc.
Integration with google maps for automatic directions, adding notes, and then taking all this with you on email, online, or your mobile, is so helpful.
So if you want help with making and sharing travel plans, try it.
