Our family was last in Kauai in April, and I finally got our blog organized enough to post here. It includes six trips over the past two years. It includes four of my husband's solo trips (due to work) and the two family trips which we brought small children (a toddler and a preschooler).
I hope this helps others to plan their trips. I got a lot of advice from this forum and I want to contribute back. It's probably too much to scroll down and read so I put a lot of labels on the sidebar to help you narrow it down to what you are interested in.
If you are interested in the activities we did with the children, those trips were in March/April 2012 and June 2010. You can just click on those dates in the blog archive (below all of the labels) and scroll.
