Green Turtle Bay is always a great place to stay. They did go above and beyond to satisfy any of my concerns. Their repair facility seems to have problems with mechanics coming to work or getting qualified mechanics. I do not think this issue is unique to GTB, but I have seen it at many, many marinas. They do the best they can.
Thoroughly enjoyed the marina. It is a simple, family owned business with fishing apparel store, bait store, and a very nice restaurant. Folks were very nice and accomodating.
