We had a great time in Oahu and having a reliable parking spot in Waikiki was a huge relief. The place was clean, well appointed, and had a sweet view.
Getting from the room to the private parking garage was the only minor hiccup, only one of three elevators serves the parking garage and when you call "Down" from floor 12 it's never the right one.
Pro tip: You've gotta head down to "L" and call another elevator "Down" from there. Hit "G2" on the new elevator to open the rear door and walk on through.
