Again, remember that NCI is a barrier island and you can only get there via boat or private plane. (We personally use and high recommend Car Concierge Service out of Ft Myers (239-313-9005) tell them Bennie sent you).
Most guest take the ferry over from Pine Island using the ferry operated by Island Girl Charters. Regardless of how your arrive/depart either by ferry (Island Girl Charters) or private boat, this area to the left of OTW restaurant as you come into Safety Harbor is where you will want be dropped off and picked up by ferry which is incredibly convenient given that NCISeabatical townhouse (Unit 83) is just steps away.
