I like the drop off for checked bags. Done and gone, which I do early to secure favored parking spot inside the garage before it gets filled up
Pre pay and self park, leaving carry on bags in the vehicle. Walk over to Grills for a Bloody Mary on the dock to admire our new home away from home. At assigned check in time, we walk back over to collect carry on bags with a relaxed mood...check in and walk onto the ship.
With arriving early before our check in time, that favored parking spot is indeed easier to find near the elevators.
