slick- it will happen if you really want to.
We were in Kona and there is a place you can do it for a little $$$, and then the proceeds go to a dolphin protection group- worth the money in my opinion!

After we had done it, we found out about a place down the coast where there is a small cove that the dolphins come into early in the morning to feed and play. Only the locals knew about it, and it was free. I hope to go back there soon
