We did our buddy trip to Inverness this year ... middle of September. Weather was great .. We played 8 rounds in 5 days ... the courses were excellent - especially Copperhead and the Island Course. North and South were pretty nice also.
I have to say ... in the 50 + trips we've done (over 20 + years @ 2 or 3 / year) this resort was fabulous ... they had clubs on the carts for every round when we were ready to play --- the shuttle service was great. Condo's by the pools for after golf were fabulous ...
I highly recommend Inverness for a trip.
