I've only done one business trip and it was for software training a few years ago.
In our organization the admins are the ones who stay back in the office to "mind the store".
I really can't think of any admins in our organization who actually travel. 99% of us do all the organization, planning, research, packing, shipping of materials, and other prep work from the office and then brief an assistant director or manager on what's been done and what will need attention once on site. The briefing packets usually end up needing a binder to hold it all. Then they call us from the site asking us the questions that were answered in the briefing and in the binder anyway!
