No hotel is going to take your luggage for you if you are not a guest. (I'm not saying that someone might successfully sneak luggage into a bell-hop room; however, they won't be telling them that they never stayed at the hotel.) Don't understand why you just don't rent a car. Then you can go anywhere you want and keep the luggage in the car. If you've got a large group and a lot of luggage, rent a van. You'll save the money on the transfers from the port to the airport. A rental car will be MUCH cheaper than paying for the port to airport transfers and a day room at the airport.
