Nothing worse than a "zero replies" thread, so I thought I'd post a reply even though I can't come up with much by way of useful information! Unfortunately anything I would be able to tell you about Curacao is now wildly out of date - we stayed there for one night in 1988, en route to Aruba (which didn't have any direct flights from AMS then).
I don't remember anything about the hotel we stayed at; I have some memories of a shopping spree (cheap clothes!) in the morning, and of a flight across to Aruba in a Twin Otter. I remember wishing we had stayed in Curacao longer as it seemed a lot more "un-touristy" than Aruba which was full of high-rise hotels and which had quite an American feel to it despite the very Dutch-looking street signs. A lot will have changed in the last 16 years, though...
Have a lovely time!
