Just enjoyed a very pleasant 1-night stay here in January 2017. The Diamond treatment is excellent; in addition to full breakfast in the restaurant (lounge was closed), access to the spa is complimentary (otherwise $15) and I was provided with a $50 voucher to use at their "Trading Post" (aka, resort store and sundries shop). I was told at check-in that the latter is a new benefit they have only recently started offering to Diamond guests.
Service at the hotel is outstanding and the grounds and setting are quite lovely.
