The beaches appear to be smaller than the wonderful wide beaches we had in Aruba. We stayed a weekend in the area of Eagle Beach to Divi Beach on Aruba and didn't leave much other than downtown but it was very nice. In comparison, Curaçao seemed more interesting for other things if you're not after the most perfect beaches. It has more character than the area of Aruba we stayed. Aruba felt more American commercialized and we were fine for a weekend relaxing without a car. Curaçao felt more like the Dutch Caribbean and you definitely need to rent a car to get around and see some stuff. They're both cool destinations for slightly different reasons. Here's some pictures to compare to my post about Aruba.
