The ferry goes out of Davis NC, there is two services you just have to go on line and make reservations. Look up Cape Lookout, that is after the government opens back up again, the web site is down until they open back up again.
If you don't want to camp you can rent a cabin through the park service, it has hot / cold water, shower, toilet, and a kitchen (gas stove top), no power though. If you bring a generator you can hook it up to the cabin and have power. Also remember to drop the pressure out of your tires or you will get stuck in the sand. They have air available when you get off the ferry at Davis. Enjoy
