We booked very last minute; tantalizing rate and interesting itinerary. Expectations were uncertain; our first cruise with Disney set the bar pretty high.
Embarkation process was just passable, shaped by the abysmal organization of the drop-off area at Cape Liberty: A single lane of traffic feeding about 50 angle-in parking locations, with private cars, shuttle buses, and taxis all fighting to get in and out. A multi lane, multi curb setup more like an airport would make WAY more sense, and there is plenty of land / space to set it up that way.
One tip; we used Premier Parking's nearby lot and spent less than half of what other cruisers did to leave their vehicle; their shuttle service was fast and terrific.
