Honestly, with how busy Port Canaveral is these days, I haven't seen much in the way of Park and Cruise offerings for hotels.
I know friends who have used Port Canaveral Parking which is around the corner from the Disney terminal multiple times. When we cruised on the Wish in Nov 22, there were so many other ships in port and it was so busy we were glad we had decided to just park at the Port and pay the extra instead of fighting local traffic. We waited in a 30 minute or so back up to get to the exit for the Disney Terminal which is the first one.
The port is very poorly equipped to handle traffic for days when most/all of the berths are being used.
