Personally, I loved taking
DCL transportation from the resort. My luggage is picked up from my resort room the morning of the cruise, we can have a leisurely breakfast or swim before the bus picks you up. You find out the night before when you need to be ready. On the bus, they show a video on the way to the port to get you in the mood (as if you weren't excited enough already). Once you arrive, the crowds have thinned out and you can pretty much board right away. If you time it right, your staterooms will be ready, so you can drop off all your carry-ons before getting some lunch or hitting the pools. I find it more relaxing than getting a private car or renting a car and driving yourself.
