No, you cannot prepay for official onsite parking at the Port Canaveral cruise terminals; the system operates on a "pay-on-arrival" basis. When you enter the parking lot or garage at your designated terminal (such as CT1, CT5, or CT10), you will pay the daily rate—currently around $20.00 per day plus tax—at the entrance booth. This fee covers both your arrival and departure days. The port accepts major credit cards (Visa, Mastercard, American Express, and Discover), but they no longer accept cash. While you cannot reserve a spot in advance for the official port-owned lots, there is generally ample space even for the largest "mega-ships." However, if you prefer the peace of mind of a prepaid reservation, you should look into off-site parking providers like "Port Canaveral Parking" or "Park Port Canaveral." these independent lots allow you to book and pay online in advance, often at a significantly lower daily rate than the official terminals, and they provide complimentary shuttle service directly to your ship's embarkation point.
