Great laugh!!!
This was totally natural and spontaneous. When we arrived by boat around Lanai and into the harbor, we saw some dolphins swimming near the boat. Later, we saw them swimming offshore near Manele Bay Resort. We just swam out and joined them. The next day, we were swimming in the harbor and saw them again. Then while leaving the island, they swam around the boat, and the captain did a wide 360 and they swam with the waves.
Great memories.
