She is a great seasoned coordinator that has an eye for detail and how to help alleviate the stress with a itinerary.
There are a few things I would change to her itineraries:
1. Be broad. Let the person know what time they are supposed to be there and tentative times for things.
2. I would allow more time in between especially around pictures. There should be at least 30 - 45 minutes of extra time. You never know how pictures will go.
3. put directions in the packet if you do not have a limo or bus picking you up
4. put in rehearsal items
5. try to get them out before the rehearsal dinner
