As shutterbugs, you'll find lots of photo ops at all these stops. The architecture in Curacao is stunning and it's one of the best places to be able to absorb local culture. Lots of beautiful scenery and plantlife on St Thomas and St Martin, too. In Aruba you can rent off road vehicles to go off the beaten path. I recommend a stop at Casaberi rock formation. Although it was very crowded when we went there, I explored a bit and found a couple of quiet corners with interesting photo ops and very few people.
