The DCL tour I was referring too is the other bus company and just gives you the one day ticket plus the transfer from port to bus station and then from bus station to either Miami International or Fort Lauderdale airport.
My honest answer is I don't know but the bus company themselves also offer it on their website so even if DCL do not offer it its worth contacting them as they may be able to do it for you directly. Its called the Cruise to Short package. I would email and they should be able to tell you if they are offering this on the December one already as they told me about it for the WBTA (September) in Febuary when I spotted it on the DCL website
