Wayne,
Yes, of course I should have included Stonewall. And from Philadelphia, I'd say Atlantic City CC and Hidden Creek are certainly less than an hour--about 45-50 minutes as you say.
I didn't put the courses in any particular order though my feeling is that both Huntingdon Valley and Rolling Green are more interesting architecturally and better courses than Aronimink. Yet there are a lot of knowledgable folks that feel as you do.
