I attended a conference in Honolulu and Karen's place was perfect. It was a mere 10-15 minute walk to the convention center, but was located perfectly in Waikiki to where you could get almost anywhere with a reasonable walk. Parking on site was easy but cash only so be prepared. The only negative I can give is the elevator system in the building is hard to work (only 1 out of 6 elevators actually went to our floor) but this was never a true issue for us, just kind of annoying. I would highly recommend staying at Karen's place!
