Well go see anyway. Talk to him about it, and what his plans are...are they moving, downsizing. He may not want as much as you think...and if not many people come, he may come down later if he is too high to begin with. All I know is that you may be kickin' yourself if you dont go see.
And it will give you a chance to wish them well. Go see, there is no harm in that. good luck!
