You have covered your bases except for one small detail. Hang your "DO NOT WASH" note on the dash where it will be seen by anyone who gets behind the wheel to move or drive it.
If you post your note on the steering wheel, someone's going to remove it and set it aside when the car is moved, then you can't control who sees or doesn't see the note after that.
My advice comes from 30 years in a new car dealer's sales and service departments.

I"m with Bill on this one and have posted pretty much what he's posted for years on MOL...
You can't take chances for all the reasons Bill stated and others...
Keep this in mind...
If they do wash it and in the process instill swirls and scratches, then not only do you have to remove the swirls and scratches but now you'll have less paint on the car to last over the service life of the car because removing the swirls means removing a little clear paint.
And the scratching, the buffing and the removal of your precious clear coat can all be avoided if you can just get them to not touch your car.
What's strange is no is is bright enough to look at your car and think to themselves...
"Wow! This car has a really nice finish"
In other words... there's no need to was it...
I went through this same dilemma with a brand new black Honda Pilot I owned and we printed out nice signs that said, Don't Wash and taped 3-4 in the inside of the windows.
We told the Manager and anyone else that was involved...
"Don't wash or wax or anything...."
Good luck... Maybe print out the below two articles and hand them to whoever you have to deal with to get your point across... take your
swirl finder light and shine it on one of their cars and then on your car to show them what you're talking about.
