"Have you (or anyone) had any good experiences at Atlantic country club, Ballymeade or how bout the Reese jones at Pinehills?"
GCA delights, on Cape, are all private - Eastward Ho!, Oyster Harbors, & Hyannisport. Kittansett in this class but not on Cape (Marion, MA)
Seems like you are looking for public Cape golf. Yes, there are options...all better, IMHO, than Ballymeade & Atlantic.
Cranberry Valley - good
Captains (2 courses) - good
Bayberry - better than previous 2 and I understand they just spend $$ on a refresh (haven't seen the refresh)
Cape Cod Country Club -- 15 holes of very entertaining golf...last 3 holes weak. I prefer over previous 3. Volcano par 4 14th a favorite of mine. Longish ride from Truro, tho.
Ocean Edge is a resort with an entertaining golf course...I believe open to public in Sept. -- over-priced but enjoyable
Dennis Pines - good, a mite boring
Pinehills both courses excellent (Jones better than Nicklaus course)...but, not on Cape, in Plymouth...a long drive (1.5 hours) from Truro
