I've heard others doing this.on our last trip but it's beat to confirm.
You should call them.
You can stay and cruise, cost $5/day for parking. Free ride to airport, but $8/person to cruise terminals. We paid to park and Uber to terminals ~$7. Very nice hotel.
We had no problem getting a space to park through the Carnival website. It was $15 per day & well worth it since it was just 30 or 40 yards from the cruise ship.
They usually do allow it for a fee if they are not heavily booked. But you should call the hotel and make arrangements ahead of time. The staff is excellent at this hotel and are very accommodating.
