Yahoo! Trip Planner
Trip Planner is a tool on Yahoo! Travel that lets you save hotels, attractions, restaurants, maps and more to a customized travel guide. You can add travel dates, your own comments, even bookmarks for other sites to your trip. Once you’ve created your trip, you can print a copy to bring with you, or access it from any computer with Internet access.
UPDATE 7/11/2006:
Trip Planner has gone out of beta.
