I just got off the Summit in Miami on April 25. I did self-assisted disembarkation. We gathered in the Rendezvous Lounge Deck 4, Aft and people started queuing up prior to 7:30am disembarkation time. They let us off a few minutes early. Once inside Terminal G we stood in front of an iPad like device which took a picture of your face and once the facial recognition identified you, you were free to walk off. It took less than 10 minutes from the time they let us off the ship until I was outside arranging a transfer to Miami International Airport. ($10 cash per person using a shared 14 passenger van, no reservations necessary)
