Tish,
leaving the centre of Santiago behind you (heading west sou west as I recall), go across the iron bridge, continue about i mile & just after the petrol station (30 yards or so) turn right up the hill. Continue along this road until you enter the golf club ground itself!
Price of green fees WAS (last time I played there was earlier this year) RD $800 for non members, RD $600 for FedoGolf members. Buggies are RD $600 as I recall & caddies are upwards of RD $600 depending on how good they are (or how good a round you have had

!!) Watch out if you get a hole-in-one though, there is a telegraph system back to the caddie house which defies belief & they are there to claim their free drink/hand out or whatever!!
YES ada,
There is an EXCELLENT professional there called John Allen. His rates are very reasonable as this is a 'LOVE' of his!! I always try to see him when I go that way as my swing leaves a LOT to be desired!! ~ Grahame.
