Mark:
I would have been happy to host him at my club, but I will be out of town. I suspect, though, that a call or letter from someone from Royal Cinque Ports would get him on a number of the private clubs in the area. I would start with Columbia CC b/c of location, quality, and possible receptivity to such a request.
With respect to public courses, if he's staying in the city (which I suspect is most likely), I would recommend Westfields, which is much closer than Whiskey Creek; somewhat closer and (IMHO) much better than Blue Mash; and somewhat closer and with less housing than Stonewall. I haven't yet played Lake Presidential, which is a similar distance and apparently pretty good.
