Get one of the free golf magazines when you first get there and look in the back for special offers. During the off season I was able to get green fees and a cart for under $35 at several places with the coupons. A lot of the cheaper courses are off the island, but still kinda close. Harbour Town has a flat fee of $240 if you want to play there...(not me Babe).
I have some links to golf course info included on my web site.
