Ihilani Marriott Resort is out of rooms for 4 people from 2/24 to 2/27. Turtle Bay looks pretty good to me. I see the wisdom of not changing hotels, but also have heard about the laid back North Shore and would like to experience it. Leaning toward not changing hotels if all 7 days will be in Waikiki.
I'll be looking into the other options and will post what my thoughts are.
Thanks for the great suggestions.
