On both of our cruises, we saw the dolphins that hang out around the port.
When we were in Curacao, there was a family (pod?) that would swim past our condo every night. We only saw dolphins once in Bonaire this past November. My friend and I both have this thing for dolphins.
That's one of the reasons that I like staying at the Mirage in Las Vegas...I can go out and see the dolphins. It's so peaceful back there late in the afternoon.
I bought an interesting dolphin ring at the Mirage. It's basically a diamond solitaire, but it has a dolphin that rotates around the diamond when you move your hand. They're made by Teufel. They have others, but mine was the only one with the dolphin.
