Since our stay slightly overlapped the OP's, I'll add my thoughts here.
First time visitors (me, DW, DD 15 and DS12). Spent 7 nights (7/5-7/12) in a 1br island/garden view villa. Own at SSR & OKW, so felt lucky to get the island/garden view.
Arrival: We're from PA, and decided to break up the travel by spending a night in Los Angeles going and returning. That allowed us to get a good nights sleep and still arrive at Aulani around 12:15pm. Pulled up to the front doors and handed our luggage off to bell services. We tipped of course, but not the $5/bag suggestion I later saw printed on the claim ticket. Then it was off to self-park and check-in. There was a pretty lengthy line at the front desk, but then I noticed a"DVC Member" sign at a different line with nobody in. That got me the next available cast member at the front desk. As expected, the room wasn't ready yet and they would text me when it was.
Waiting for the room: We went and got some pictures with 'Olu Mel, then hit up Ulu Cafe for some lunch. They could definitely use more seating for dining. After lunch was more pictures from around the lagoon. Just as we were about to go into the gift shop, got the room ready text. Only 2:40pm! Based off of my luck the past few years at WDW DVC properties, I was betting on getting a room significantly later than the 4pm check-in time.
The room: About 6 weeks before our arrival I put in a room request with member services: Ewa building, long wing, high floor. From others on the boards here, this seemed to be a popular way to get a view of the luau, and a view of the ocean... all from an island/garden view room. We were assigned room 1671. Top floor, first room in the long wing. Beautiful view of the ocean to our right, and the luau right below us. Close to the elevators too. Couldn't ask for a better location based on my request.
Resort Days
Saturday, Monday and Thursday were basically resort days for us. The chair game is ridiculous. Luckily, DW never fully adjusted to the 6 hour time difference and was awake by 5am most days. We made base at the Ka Maka Grotto pool. Saturday she scored us some 2nd row chairs on the cabana side about 8:15am. Monday some 1st row chairs on the cabana side around 7:40am. For our last resort day, she really wanted the front row (next to the infinity edge) looking out over the lagoon. She got there about 5:15am to get those. The row filled out with the next 2 groups arriving around 5:30am and 5:45am. We spent most of our time cycling between lounging and hugging the infinity edge with the occasional lap around the lazy river, or cooling off in the lagoon.
Trips
Sunday morning we went to Pearl Harbor. Visited the Arizona memorial, toured the Missouri and some museums. Then hit up the Aloha Stadium swap meet for some souvenirs and a food-truck lunch.
Tuesday was a trip to the Dole Plantation (DD love Dole Whip and all things pineapple), a walk through Waimea Valley to the waterfall, and some exploring on the North Shore and Haleiwa.
Wednesday we went to Kualoa Ranch and did the side by side tour, which was outstanding. Even the drive to the east side of the island on the H3 was a sight to see.
Food
Since we had a 1bd villa, we did a light breakfast and usually one other meal in the room. This required a grocery trip that we did on the evening of arrival day. Had a chat with a cast member on our way out, and mentioned that we were heading to the Costco in Kapolei. They said "good luck". I should have heeded that omen. Costco was crazy busy. There were dozens of cars just cruising the parking lot trying to get a spot. After about 10-15 minutes of parking lot torture, we parked behind the store. The inside wasn't much better. Ended up leaving and heading down the road to a
Walmart.
We're not much for seafood, so no shrimp trucks or poke. We did go to MonkeyPod. DW was a bit irritated about the $9 lemonade that DS had along with a $9 refill. We also stopped at Seven Brothers Burgers in Haleiwa, which was good. Had some food from Ulu Cafe, and the pool-side service. Everything else was from random food trucks along our journeys.
Overall
Really enjoyed what we did on the island. Loved the resort during the day. Other than the DVD member celebration one night, there really wasn't much to do in the evening. I do wish there was more to do at night. We've been cruising a lot these past few years, and we really enjoy all the night time entertainment and activities on the ships. Likewise, our WDW and DL trips are usually spent in the parks until close.
We'll definitely be back again at some point. Probably not for 7 nights though. I'd like to see some things on the other islands, then maybe spend 3-4 nights relaxing at Aulani.
