The problem with flying "around" such places is the instrument approach traffic may well be 10 miles + from the field, so how much do you avoid?
Perhaps better to talk to them and route overhead, at least they know where you are and can negotiate safe transit.
If they get silly, ask for the SATCO's telephone number and talk to them on the ground about it, worked for me on the few occasions it has been required.
