Just something to keep in mind - when AKL opened, they didn't let anyone but resort guests drive into the resort when it first opened because so many people wanted to come in and look around.
Although I have not run into this situation at any other new resort, there is always the small possibility that if they start having a lot of people driving in to AOA just look around, especially while there is still construction going on, they could opt to restrict access by car to the resort for a while.
I would probably go via Disney transportation instead of taking my car anyway. Construction sites are a great place to pick up nails in your tires - not something I want on my vacation.
Personally, the only time I have been refused entrance to a resort was once at CR when they had a huge convention in house and weren't letting anyone but guests in. But since the resorts you mention are not attached to parks, you shouldn't have a problem.
