Beauman,
I would suggest first of all coordinating with the local air field or air show boss to arrange for the fomation flight arrival. I would strongly recommend everyone arriving at a nearby airport, then departing together at a coordinated time from that airport to the airport where the show is being held.
The question is do you guys plan to land as a flight or land seperately, this detail needs to be worked out prior to arriving. With prior coordination and attention to details just about anything can be worked out.
