I've been using TripIt for years. Have it on the iPad and iPhone but mostly use the website through a desktop to build up my itineraries. Not just hotels and flights but custom notes and custom maps. It lets you attach photos and screenshots to any event.

However, they recently rolled out a new version where they display attachments only as thumbnails. So when you print, you don't get the attachments printed out at full size.

Really a bad loss of functionality and I'm not sure why they even went to the new format. Don't really see any benefits.

Now, if you can cache itineraries on your devices so that you can view all of it without an Internet connection, which is often going to be the case overseas, then I could work around the printing limitation.

But as it is, all these detailed itineraries from my past trips, I've converted to PDF to save on my own devices, in case the service goes away or they do incomprehensible things like take features away.

I looked at other sites, like Kayak, Orbitz, Expedia and Worldmate so far. They all let you forward emails and automatically enter that info. Some let you edit and add events manually. But so far, NONE of these other services let you attach screens and print them out.

Then there are services which will auto-populate a custom guide with places you might want to visit. Stay.com is one example. But that's just letting you pick blocks of places with boiler plate info and not letting you customize.

Plus all these services seem to want you to connect to a social network, use a FB login. I don't know, people who blab about their vacations are as boring as those who always shows you pictures of their children or vacations.
