Having sailed out of San Diego and Miami, the port experience at Port Canaveral is way easier and more intuitive. You'll follow the signs to the Disney terminal (#8). Once you pull into the terminal area, you will be directed first to the luggage drop off area. There, you'll drop off with the porters any bags you want taken directly to your room. Bear in mind that these might not get to the room until late in the evening, especially if there are electronics inside that have to be checked. Some like to carry a bag or two onboard with them, to have swimsuits available to enjoy the pools before the luggage makes it to the room, or to keep up with valuables that they prefer not to lose sight of. Also bear in mind that you'll have to carry on any drinks you're bringing on.
Once you drop off your bags, you'll make a couple of left turns into the parking garage (just follow the line of cars) and find a parking spot. From there, it's a short walk across the bridge to the terminal building.
