I haven't been to Grenada in a while, but my trip reports are on my webpage here:
Islandtime. Also, if you visit the Fodor's travel forums, there are several posters who have been to Grenada and posted their trip reports, one of whom is "ejcrowe" -- look her stuff up.
Bottom line for me, even though I haven't been in a while, is that while difficult and potentially expensive to reach, Grenada is a gem. An unusual combination of lush rain forest and white (and golden and grey and black) beaches; spice plantations and rum distilleries; friendly people and terrific local cuisine. And not overly expensive once you get there.
