Hi prattba,
I believe what you're looking for is the "fly/drive" packages. Many companies offer them and all with different arrangments, customizable to your trip. There may be some restrictions so be sure to check up on that. I've seen a few that have required
at least two inter-island flights.
Simply type "Hawaii fly/drive packages" into any search engine and you'll find a variety of companies.
You can give this
site a try.
Congrats on the wedding. Let us know how your trip goes. Happy travels!
