Steve,
As for Cathedral of the Sea, I'm cheating myself, reading in English. Whenever I'm off the island my Spanish deteriorates rapidly. Plus, most of the Spanish I speak, which isn't enough or very good, I learned from my Colombian friends. They laugh constantly but in a good way.
There's now a flight from Madrid to Aruba, a 747 charter I think. People come for 1 week at a Riu hotel and the second week on a cruise. I'm meeting more and more Spaniards and enjoying that immensely. I'm surprised they would find the Caribbean interesting given how much history and great port are around the Med. But, I suppose many of them have done those places already. There is also Spain's tremendous influence in the region. And yet, Aruba is a quasi-Dutch island. Bizarre.
