We are actually on Oahu this week. It's my first time and its wonderful. We traded into Marriott's Beach Club at Ko'Olina. So we are just down the street from Aulani! and we have seen changes in the few days we have been here.. they are busy working

It seems I managed to get here without the charger for my camera so I am not sure if I will get pictures taken of the site.
The Ko'Olina area is beautiful. We hit the beach tomorrow so I can't officially say yet, but it looks wonderful. Apparently at lagoon 2 they have a daily fish feeding, it has been happening for years and is really popular....with the fish. Large and small, I was told its a sight to see. Aulani is at Lagoon 1 and we are staying at lagoon 3. They have walking path that goes by all the lagoons (1-4) it is 1.5 miles each way.
They have a number of upscale restaurant in Ko'olina. We haven't tried any, as we are here with our 3 and 6 year old and we are going more casual this trip
Just one freeway exit down is a new costco and target. A bit past that is a safeway, longs, etc. We also saw the general assortment of fast/casual dining in this area - McD's, Pizza Hut, Chili's, Jamba Juice, Starbucks, KFC, Taco Bell, etc.
For us the location has been great. We did get stuck in a bit of traffic today coming back from waikiki around 5, but we were leaving the hustle and bustle and that felt good. We look forward to returning and being able to stay with Disney next time
