I've been to Maui, Kauai, and the Big island. With smaller kids, I'd vote for Kauai. Some awesome swimming/snorkeling spots, the playground at lydgate park is amazing, and the scenery is incredible. It's quieter, more intimate. Maui, is more expensive, and touristy. The beaches are the best on Maui. Maui is my favorite, but with kids, I like Kauai.
