The unspoiled island of Molokai takes you back to how the Hawaiian Islands were before mass tourism erupted in the 60's. There's only one hotel, and that's the Hotel Molokai shown below.
A visit to Molokai is an easy addition to itineraries from either Honolulu or Maui. If you're good with simple accomodations with some truly jaw dropping views, a few days here is worth the trip. Sightseeing trips depart directly from the Hotel Molokai.
