She can head off to wherever she needs to be, and you can drop in to REXPO.
Too easy
In all seriousness (is that a word?), while I may not be free at 17.30 hours due to other commitments, if you can make it to REXPO - just down the road from airport, I can drop ya wherever afterwards. Even if it is Gingin. The drive dont bother me, I'll do it for shits and giggles.
Just a thought.
