Does someone have a template/checklist they use when traveling?

It's a new fiscal year and I'd like to start on the right foot for a change. Usually I cram a sticky with flight information, a sticky with hotel information, a sticky with weather, maybe a downloaded map or two and my travel orders into my organizer. It gets the job done, albeit poorly: I always feel like I've forgotten something vital before I even get to the airport.

At a former employment locale, I can remember the Executive Assistants ginning up a one-pager for the Executives with all their pertinent travel data. Sadly, I wasn't an Executive, so I don't have a copy.

Lacking a set template (which I'm happy to create), what do you consider essential travel information?
