I went on the 2 hr dolphin cruise twice. Both times we saw dolphins, many dolphins, riding in the wake of the boat, following barges and playing!
The captain is very knowledgeable of the wildlife in the area and has worked with dolphins, so has many stories and anecdotes.
This tour is good for old and young alike.
My one bit of advice....even if it is warm on shore, it will be cooler on the water. Dress appropriate,t
