If you stay around Grand Anse beach, you are only about 10 minutes from the airport ( BA twice a week and VS once I believe, both have a short stop on the way), which is small and easy. All the places listed in my earlier posting I went to for Business, but of all these Grenada would be my first choice for a holiday.
The Coyaba is well located and quite reasonable when I have visited, with a nice vibe.
How long are you planning on staying there? There are two much smaller islands, but suggest you get the Bradt travel guide on Grenada, which I think is the only quality dedicated guide book.
Bear in mind that a few years ago the island was devastated by a hurricane, which affected over 80 percent of buildings, as well a some of the rainforest. If you travel around the island there are lots of things to see and do, and bear in mind it is not called the spice island for nothing (+ nutmeg).
Of, and if swimming in the sea, make sure you have goggles, was very close to a lionfish there!
Also as mentoned in an another post, with LIAT is is easy to have a two centre holiday just to see another place while in the area.
