I found this site last year when I was looking for Capers for the 5 day to Grand Cayman & Cozumel. There are several posted here- maybe one of them is the itinerary you're interested in. Some are a little old, but some are newer.
It sure would be nice to have a specific place to go to where we could see an actual Carnival Caper for each ship. Most of us are curious and then there are some who like to plan ahead, get the most out of their vacation.
I'm sailing on Carnival Paradise May 5th 2008. If anyone is interest in the Capers let me know!
