Booking hotel/bnb in Okinawa

Hi guys I am heading to okinawa in Japan and debating on whether to book a place in the main island or one of the remote islands (Zamimi or Tokashiki islands or any recs) . The hotels are cheaper in the main island was thinking to just take a ferry there for the day. Any suggestions on hotels? is it more convenient to stay in the remote islands or best to stick with the ferry?
