Take a cab and relax. You will thereby avoid time spent securing rental car and other nonsense. You will need it, flying all day is tough.
You can purchase enough provisions for the night at the little Orient store.
The next day you can rent a car right on site at Club O. (It will cost about more than going with one of the traditional airport options but not much more.)
And there are grocery stores nearby to stock up for the week, but again, it will be the next day so you'll be up for it.
