We (me, wife and two daughters) really enjoyed staying in this place. To be helpful for other visitors afterward, I am leaving these comments.
1. The place you will be staying has several names such as Ilikai hotel, Ilikai apartment or Ilikai hotel & luxury suites. It's all the same building. So, if you are using a rental car, try to find the Ilikai hotel. That will be the place you will be stating.
2. But, if you want to park your car, then it could be a different story. If you want to use valet parking ($28 per day), then you can arrive in Ilikai hotel. If not, then you better use the parking lot at Ilikai marina condos. It's a different building from Ilikai hotel, but sharing the parking lot together. So, park your car in the 2nd fl. at Ilikai marina condos ($20 per day) and use the bridge between Ilikai marina condos and Modern Hotel to reach the lobby fl. at Ilikai hotel (these three building are all connected each other)
3. To go out to the beach, you don't have to use the front gate of Ilikai hotel. there is a path connect the lobby level of Ilikai hotel and the beach. Front gate is only useful for the valet parking for me.
4. Ala Moana mall is only 15~20 walking distance from the hotel. You may try to reach there without a car. Sometimes local people are not much friendly when you are not good at driving, and Ala Moana has good chances to have traffic.
5. We used Korean supermarket and Walmart nearby. All the types of bowls and cups are already in the hotel. Only one thing we missed was a pair of scissors. We couldn't find it in drawers.
In summary, the place has everything (except the scissors) and very good access to the beach and the shopping mall. Good view like the pictures. We will definitely use the same place if we come back again to Oahu.
