Maui (again i know)...and Oahu

I have searched and there are a bunch of threads about Maui but I noted several people went this past summer potentially? I wondered if there were any new hotel or condo recs? We are a family of 5 so 2 bedrooms would be great. My inlaws may be coming as well but would get their own unit I suspect. Also any activities that a 13, 10 and 7 year old would all enjoy (plus 2 folks in their lates 70s and DH and I) : )

Also, any suggestions on where to stay for a couple of days on Oahu? My inlaws would like to see Pearl Harbor.
Thanks!
