I am tempted by Discovery Cove, though. It's a little out of our budget but that could be a special trip. My DS9 is still a little too young but we'd have to do it before my DS12 gets too old (and thinks he is too cool for a family vacation). Maybe in two years' time.
I think that Antarctica thing they build looks so junky. Nothing like the concept art they promised us. Looks like they cheaped-out on that.
I have no interest at all in this "Yonaguni" thing, whatever it is.
