I am interested in seeing the Manatees near the Port also.
I have two DGDs that are fascinated by them and I found a good way to hold their interest and give them some education about the Manatees. There is an organization called 'Save the Manatee' that is very active here in Florida and the singer, Jimmy Buffett, is one of the co-founders.
I pay the annual dues of $25 for them and the girls are able to 'adopt' a Manatee. I let them choose from the Manatees that are offered and the subscription fee collected is used to help support them at the State Park where they return every winter. I insist that they choose one of the Manatees that is known to return to a place on the same coast where I live, so we can visit the Manatee in December when the family comes down to visit us. One of the locations is at Blue Spring State Park, near Orange City, Fl. It's about 40 miles southwest of Daytona Beach with an exit off of Interstate 4.
During the winter months, many of the Manatees return to the warm springs where they were born, or where they have found to be comfortable. They usually migrate starting in November and return to the ocean waters in March.
Here's a link to the Save the Manatee site:

When you adopt a Manatee, you receive lots of information in the mail about them, including photos of 'your' Manatee and a biography of it. Both of my DGDs really enjoy it and they have done school reports about it. I recommend it highly.
hope that helps
