Kryos: Did you ever get the recipe for a Tropical Cable Car. I did an internet search and found that Holland America got the idea from a bay area drink called "Cable Car" this is that recipe from the absolut website:

My best guess to make it tropical is to sub lemon juice for pineapple juice. I will need to test this a couple times.
