If it is the same place, it is an awesome experience. We went to Crystal River, I cannot recall the name right now. We were just searching and found a place directly behind a hotel on the main road in Crystal River. It was a mom and pop type of place and received the best experience ever. We were the only three on the boat so it was like our own private tour. We saw a few manatees and were able to swim with them. We also chased dolphins (by boat, of course!) We ventured back to a place called 3 Sisters. It is a natural spring and it was incredible! It was wierd bc we swam back into this area that looked like it was river that went no where but then it opened up to the area where three natural springs are. If you do this be sure to wear a life jacket even if you are strong swimmer. It was a long haul and I did not expect to tire so easily. It was like looking thru a glass of water the water was so clear and refreshing. I actually freaked a little because I felt like I was going to fall it was pretty deep and you can see ALLLL the way to the bottom. Google it, there are some good photos available online. But seeing a picture is nothing compared to the real thing!
HAve a great time!!!
