Journy is a concierge that plans your entire trip for you, hour-by-hour.  Me and @suzywillow used it in Lisbon last year to help decide which restaurants to visit and sites to see.  It's great for people like me that dislike planning. 😊

Kayak is the ultimate travel planner. First it searches the cheapest tickets, hotels, and car rental via dozens of other sites. Then you forward reservation or ticket confirmation emails to its email address and it automatically creates a trip plan for you. Finally it sends email and SMS reminders and notifications about your trip schedule and issues.
