The closest hotel to the wedding venue is Turtle Bay Resort. It is on the other end of the North Shore from the wedding location. Ideally, it should take 30-40 mins to get there, but sometimes with beach/surf traffic, it can take 1-2 hours since there is only one road. If you do want to stay there, please give yourself plenty of time to get to the wedding events.
If you prefer to stay in the Honolulu area, just make sure to allow yourself enough time to get to the North Shore. You can rent a car, or take Uber or Lyft (if you don’t have a DD in your party ;).
