Of all the Pinehurst course see if you can play #4, (and of course #2 at least once). On my list, #4 is second, followed by 7 and 8. Does anyone know what if any progress there is on #9 and #10? I know they have packages that have you play #1 and others. I would only play #2, #4, #7, #8 and skip the rest
Dinner in the 1895 room is recommended, the breakfast at the Carolina Inn is the best breakfast buffet! Forest Creek. (private) is must play if you can get on, maybe have your pro call to see if they do outside play (I doubt it for that size of a group but you never know).
If you elect to stay at Pinehurst the villas are the way to go, 4 bedrooms shared by a common living room, great fun!.
