I'm afraid you are in a kind of difficult micro climate for links golf, as, incredibly,m there are no true links on the southern coast of Ireland (i.e. from Rosslare to Waterville) despite what the folks at Old Head might tell you.
Bantry Bay is not worth a detour, but it sounds like you won't need to take one to play it! It is a very friendly place, with great home made soup, and an idiosyncratic layout that was half designed by Eddie Hacket, and half by Christy O'Connor Jr. It is distinguished by having more holes where the green is invisible from the tee than any other course in the world (OK, I haven't checked them all) and probably the least satisfying climb to a tee that I have ever encountered. Both the silliest and most spectacular holes are on the Oconnor half which is closer to the sea.
But is not a links.
As mentioned in other posts, Dooks and Waterville are your nearest links options and both hugely enjoyable. Little Island your best parkland option, followed by Killarney and possibly Ring of Kerry.
Have a great time.
