Yes, we’ve rented a car for our entire trip. 15 nights, Budget Rental, approx. $1300. That said, we absolutely love hanging at the resort, it’s super fun, and my recommendation is always to enjoy Aulani as much as you can. If you’re beach, pool, lazy river people who want to maximize your time, it’s best spent right here.
We rented a car because we’re here for over two weeks and wanted to have the option to check out some other sites and activities on Oahu. But if we were here for a more limited time, we’d just stay at Aulani.
