Hi, ground transportation is a good one.. Depending how many u are, is it worth it for you? The first time we went that route.. After that we discovered other ways.
We now get a pickup at the airport to our hotel, and then taxi to the port the day of the cruise... If you are only 2, I would go for Disney transfers, otherwise, it really is not very economical....
As for the buses, when we did it, the first one departed the airport at 9:30 AM, I believe they run back and forth all day..
