The suggestion by BDAttitude could be a valid plan B. Perhaps plan C could be to bring her in on a trailer, at least for part of the route? My own pride and beauty came from Hungary that way, we rode the trip from Friday evening till Sunday evening. 't Was one hell of a ride, though. The advantage is that weather cannot spoil the game; the disadvantage is that one must keep driving: whenever one stops there will be all kinds of curious people circling the plane - not all limiting their curiosity to looking. So you need to be two drivers, at least ; better three.
