Honolulu Airport is the only airport on the island of Oahu.
Southwest has been having great deals on flights to Oahu and neighboring Islands. The kayak app is very user friendly for checking flights and hotels as well.
Most hotels on island are located in Waikiki or Honolulu by the beach. There is an amazing resort called Turtle Bay Resort on the North Shore and close to the venue. The Marriot of North Shore Oahu is located right next to Kualoa Ranch and the Polynesian Cultural Center where they have one of the best traditional luaus on the entire island!
Dress code is on invitations but please wear muted colors and light clothing as to assist photographers with the brides vision. Also remember that Hawaii can get very hot so sweaters and jackets will most likely not be needed. Flowy maxi dresses for women. Ladies remember that the ceremony is on beach sand, and reception is outdoors so heels may become difficult. Simple khaki pants and light collared shirt is fine for the men. *please no crazy aloha shirts*
