You seem to know a LOT about cruising. I am thinking about a last minute vacation over Christmas. Am I crazy to think that I might get a good deal on a cruise? We're planning on the Riviera Maya in Feb 2008, so I'm trying to figure out where we can go. We'll be off work 12/22 - 12/30. We can usually get some better airfares out of St. Louis, Nashville TN, Louisville KY, or Indianapolis.

Any suggestions on where to start & what to look for...or is this too broad of a question?

Thanks in advance!
