i stayed at the Sheraton Princess Kaiulani earlier in April this year, absolutely loved it.. booked lowest room and received a huge suite with a jetted tub on the top floor overlooking waikiki beach
I looked through dates dec 5-15 and you can stay at the Kaiulani for ~$100 a night by using
www.getaroom.com . You will still earn Starpoints etc, but u will be saving 50% off of your current $200 a night rate
