Hi David and Patrice, and welcome to cruise-chat.
Our sister site, http://www.hawaiiportreviews.com/
contains a great deal about Hawai'i cruises. On the left side of the page is a border... scroll down, and there are links to individual ports.
I haven't cruised to Hawai'i, but have been on Celebrity Infinity. While our son didn't use the kids club, we checked it out and it looked pretty nice -- lots of activities for most ages. If you want some time to yourself away from the kids, visit the Thalassotherapy Pool area. It's adults only, and was my haven during our cruise. My husband and I took turns going so that someone could stay with our son.
What did you enjoy about HAL? I've cruised HAL as well, so perhaps I may offer some comparisons.
