While most cruise lines offer transfers, going to Orlando may not be your best option, time-wise. It's an hour each way to the port, which means you'll only get a max of 7 hours. Plus you have to eat, which takes another 1-2 hours (depending on if you're having both lunch and dinner there), leaving you only 5 hours in the park. Something like Disney can't be seen in less than 2 days, when you think about how much there is to see an do in the park. You'd be much better off adding a Disney trip before or after the cruise and then going to some place like Kennedy Space Center during the time you're in Port Canaveral.
A friend of mine did the Disney park transfer in October and I did the Sea World transfer last month. In either case, we only got 1-2 rides in during the 5 hours we were there.
