I'd suggest using Hotwire and then veryifiyng (or at least doing your best to) which hotel it is on betterbidding.com I am going to Curacao in a few weeks and saved bout $100/night using hotwire on the Hilton so I can vouch for the fact that they do include Caribbean hotels at good deals. I use htem frequently in the U.S. and Europe and I have enver had a bad experience.
