You can plan it yourself. This does take a lot of planning. If you are going very basic, just the two of you on a beach, all you really need is an officiant and photographer.

You can go with a resort like the Kahala,. They plan weddings routinely and have planners on staff. Also very pretty locations to wed.

You can choose a large non Hawaiian company such as Luxe. Even though they aren’t in Hawaii, they do many, many Hawaiian weddings and have vendors they use frequently. They are well respected in the destination wedding community.

Or you can choose a local wedding planner. They may have contacts that a non local company wouldn’t have. They also may be able to provide packages that aren’t available from non local companies.

You didn’t say which island so…
OAHU He can also provide photography.
MAUI They are located in Maui, but will travel to the other islands.
KAUAI
BIG ISLAND They are located in Honolulu, but can also do the other islands. They are also a travel agent and can help book your airfare and hotel.

Hope this helps to make your decision. You will have a wonderful wedding with whatever option you choose. (Some are just less stressful to plan)

Good luck.
