Where is a good destination resort to get married in Hawaii?
If you are looking for truly beautiful views of amazing waves and the island that is the most "Hawaiian", you have to head to Kauai. Caveat, there is no light life to speak of, so if you are hoping for the group to get out and about at night-head to Maui. My suggestion is to check out the Grand Hyatt Kauai Resort and Spa which is on the south side of the island or the The St. Regis Princeville Resort and the Westin Princeville Ocean Resort Villason the north side of the island.

I would check out this article which lists 39 wedding venus in hawaii. I've gone to hawaii many times, my family lives there and most resorts are set up for weddings. it really just depends on your budget and wedding guest list size. Oahu has a lot more resorts and can host more people. Kauai is more remote which is nice and personally i think the most beautiful. Maui is generally more expensive. The big island is often overlooked but the four seasons there is incredible and there are a lot of mansions for rent. You can also go the route of renting a home / estate either through VRBO / homeaway or can find a few through this (http://www.loveinhawaii.com/)
