We just did back-to-back sailings on the Dream last week and can also verify parking at Port Canaveral is pre-pay. First, you'll be directed to drop off your luggage with porters alongside the terminal on the right. Then, you make an almost immediate left into the area that leads to the parking garage. There are 3 lanes to enter and each one is staffed by someone to help you process your payment. As mmouse37 said above, after you pre-pay, you will follow orange cones that lead to actually entering the parking garage building on level 1 where your Port Arrival QR Codes will be scanned. You are then directed to a parking spot on level 1 to complete your covid testing. Your Safe Passage QR code will be scanned at this time and after swabbing you'll be directed to park anywhere on level 2 or above to await Safe Passage notification (by email and on their website). Then, you just gather all your carry-ons, cross the street to the terminal building, check-in downstairs, go through security, up the escalators (or elevator), and wait in the terminal until your boarding number is announced. Easy peasy!
