Overall, this is an excellent resort. My husband and I came here for our honeymoon as a part of a multi-island Hawaii vacation. We chose Aulani because my family has a DVC membership.
The staff ("cast members") are excellent. The resort isn't overly "Disney". The pools and beach are lovely. It's a very comfortable place to stay.
It's a Disney resprt, and it is consistent with Disney's excellent brand.

So why 4 stars?
First, DVC members need to note that the room on the website is not the actual Deluxe Studio, but the hotel room. The Deluxe Studio only had a queen bed not a king. Also, read the fine print -- your "ocean view" includes "at least a partial ocean view"... Which is what happened to us. I was pretty disappointed by that. I was also disappointed by the size of the sixDel studio, as I would have booked a 1-bedroom (we had the points for it), but thought it would be excessive and a studio with a king would be comfortable enough.
Second, the internet is atrocious. It was unbelievably slow. I had to take care of some paperwork for starting my IM residency, and so I was forced to go give a coffee shop because Disney's internet couldn't load my email. My husband and I needed to remotely close on our new house, and there wasn't a business center for him to take care of printing and scanning. Yes, the front desk helped us accomplish those tasks, but it was inconvenient... What high-end resort doesn't have at least a small business center?

So all in all, this is a lovely place to vacation if you can fall off the grid for the entire length of your time here. If you need to touch base on anything back home, expect to get cozy at a coffee shop.
