Just got back to our rented home after playing Waterville. Can't post much without being rude to my friends and the wives. I'll only say this for now: Shot values galore; quirk with "fairness"; green speeds that permit multiple pin positions; plenty of tee placements and angles; amazing views; friendly staff and club members; and, finally: great shots feel heroic, good shots are rewarded, mediocre shots (often) leave recovery options, and bad shots are punished severely.
I played it with rented clubs (all of ours were lost by Aer Lingus) and I had a BLAST.
