There are certain feeding times throughout the day. I think the first one is about 9:30, which is half an hour after the park opens. There is also a park employee up on the rocks taking pics of the "feeding experience", meaning they're trying to make more money. Dolphin Cove gets really crowded during feeding time, but it's fun to watch the dolphins, and touch them and stuff. It's located in the Key West section, which is right near the entrance.
